KELLY, Circuit Judge.

      Timothy DeFoggi was convicted of multiple child pornography-related
offenses following a jury trial. On appeal, he challenges several pretrial and trial
rulings, argues there was insufficient evidence to support his convictions, and asserts
his 300-month sentence was imposed in violation of the Eighth Amendment. We
affirm in part and reverse in part.
                                  I. Background

       The FBI began an investigation in 2012 into a computer server in Bellevue,
Nebraska, that was hosting child-pornography websites on the “Tor” network. The
Tor network is designed to keep a user’s identity anonymous by requiring special
software that obscures a user’s physical location.           The network routed
communications through a network of other computers, making traditional IP
identification techniques ineffective. One of the hosted websites was called
“PedoBook.” The website operated from March 2012 until December 2012,
advertising and distributing child pornography and hosting discussions about the
sexual abuse of children. On November 18, 2012, the FBI seized the computer server
hosting PedoBook, but continued to operate the website for investigatory purposes
until shutting it down completely on December 8, 2012. As part of this investigation,
the FBI obtained an order from the United States District Court for the District of
Nebraska allowing it to monitor electronic communications of PedoBook users. Both
before and after its seizure by law enforcement, agents viewed, examined, and
documented the contents of PedoBook, which contained thousands of photos and
videos depicting images of child pornography.

       PedoBook had over 8,100 members, each registered with a username and
password. Once registered, a member could set up a profile with a picture, could
request access to private groups, and could use a messages feature not available to
other users. Members with profiles were able to set up groups based on specific
interests and subcategories for posting distinct types of child pornography.

       Timothy DeFoggi, the former acting director of cyber security at the United
States Department of Health and Human Services, was a registered member and user
of PedoBook. He used the username “fuckchrist” and the display name “Ptasseater.”
He registered on March 2, 2012. DeFoggi and other PedoBook members occasionally
shared personal information, including e-mail addresses, in private messages so they

                                         -2-
could communicate with other PedoBook members and distribute child pornography
on a one-to-one basis. Evidence showed that DeFoggi joined 32 groups on PedoBook
between March 2, 2012, and December 8, 2012. Between April 19, 2012, and
December 5, 2012, he exchanged numerous private messages with other PedoBook
members expressing, among other things, an interest in the rape and murder of infants
and toddlers.

       DeFoggi moved to suppress evidence obtained through the interception of
electronic communications and evidence obtained during a search of his residence.
He also moved to preclude the government from introducing at trial what he termed
“fantasy chat private messages” sent to and from his username, arguing the messages
were not relevant and were overly prejudicial. The district court denied these
motions.

       After a jury trial, DeFoggi was convicted on all counts: knowingly engaging
in a child exploitation enterprise in violation of 18 U.S.C. § 2252A(g) (Count 1),
conspiracy to advertise child pornography in violation of 18 U.S.C. § 2251(d)(1) and
(e) (Count 2), conspiracy to distribute child pornography in violation of 18 U.S.C.
§ 2252A(a)(2) and (b)(1) (Count 3), and knowingly accessing a means or facility of
interstate commerce to view child pornography in violation of 18 U.S.C.
§ 2252A(a)(5)(B) (Counts 4–7). The district court granted DeFoggi’s motion for
judgment of acquittal in part by vacating the convictions on Counts 2 and 3 as lesser
included offenses of Count 1, and denied his motion for a new trial.

      On January 5, 2015, the court sentenced DeFoggi to 300 months’ imprisonment
on Count 1, and lesser amounts for all other counts of conviction (Counts 4–7), to run
concurrently. DeFoggi timely appealed.

                                   II. Discussion

      A.     Application for Interception of Electronic Communication

       DeFoggi argues that the district court erred in denying his motion to suppress
evidence obtained through the interception of electronic communications, because the
application to intercept his communications was not properly authorized. At the
suppression hearing, however, the magistrate judge found to the contrary, and
DeFoggi did not object to this finding. Noting DeFoggi’s lack of objection, the
district court affirmed the magistrate judge’s finding. Because DeFoggi filed no
objection to the magistrate judge’s report and recommendation on this issue, “we
review the findings of fact underlying his appeal for plain error and the admissibility
of [the evidence obtained through the interception of his electronic communications]
de novo.” United States v. Lockett, 

, 837 (8th Cir. 2005).

       An application to intercept electronic communications must contain the identity
of the authorized official who approved it. See 18 U.S.C. § 2518(1).1 Intercepted
electronic communications may be suppressed upon a showing that, as relevant here,
“the order of authorization or approval under which it was intercepted is insufficient
on its face,” or “the interception was not made in conformity with the order of
authorization or approval.” 18 U.S.C. § 2518(10)(a)(i)–(ii).




      1
        The statute states in relevant part: “Each application for an order authorizing
or approving the interception of a wire, oral, or electronic communication . . . shall
be made in writing upon oath or affirmation to a judge of competent jurisdiction and
shall state the applicant’s authority to make such application. Each application shall
include the following information: (a) the identity of the investigative or law
enforcement officer making the application, and the officer authorizing the
application. . . .” 18 U.S.C. § 2518(1).

                                         -4-
      The application submitted in this case stated that “[a] copy of the memorandum
of an official specially designated by the Attorney General of the United States
authorizing this application is attached to this application as Exhibit A.” DeFoggi
argues that he did not receive the memorandum attachment in discovery, and that
there was nothing to show that the approving judge received the required
memorandum either. The government acknowledged to the district court that the
memorandum may not have been included in the original discovery materials
provided to DeFoggi at the start of the case. Whether or not DeFoggi received it, the
relevant question for review is whether the approving judge had the document at the
time she approved the application to intercept electronic communications.

       At the hearing on DeFoggi’s motion to suppress, the government presented an
uncertified copy of a letter signed by Kenneth A. Blanco, Deputy Assistant Attorney
General. During the suppression hearing, the magistrate judge requested certified
copies of the application and the authorizing letter from Blanco. DeFoggi does not
allege that Blanco was not authorized to sign the application. See 18 U.S.C.
§ 2516(1) (a Deputy Assistant Attorney General is an officer qualified to authorize
the application). Rather, he asserts that the letter identifying Blanco as the
authorizing officer was not attached to the application submitted to the approving
judge.

      The failure to attach authorization documents can warrant suppression, see
United States v. Lomeli, 

, 741–42 (8th Cir. 2012), but here, the
magistrate judge specifically found that “the Chief Judge of the U.S. District Court
for the District of Nebraska authorized the interception of . . . DeFoggi’s
communications,” on November 18, 2012, and “[t]he application submitted in
connection with that authorization included, as an exhibit, a copy of a memorandum
signed by Kenneth A. Blanco . . . .” The magistrate judge therefore concluded that
“the authorizing judge . . . had the name of the actual, statutorily designated official
who had indeed authorized the application,” and that DeFoggi’s motion to suppress

                                          -5-
should be denied. The district court adopted this finding. DeFoggi offers no
argument as to why this finding is plainly erroneous, asserting only that “there is no
record to demonstrate the approving judge received [the signed letter from Blanco].”
But, after examining the exhibits, the court ruled otherwise. Under these
circumstances, we cannot say the district court erred in finding that the application
as presented to the district court included the necessary authorization documents.
Because the application was properly authorized, and the district court had this
information at the time of approval, the district court did not err in denying DeFoggi’s
motion to suppress. See 

.

      B.     Search Warrant

      DeFoggi also argues the district court erred in denying his motion to suppress
evidence obtained during the search of his home on April 9, 2013, because the
affidavit in support of the warrant did not establish probable cause. In particular, he
argues that there was insufficient information linking him to PedoBook, and thus no
probable cause to believe that evidence of criminal activity would be found at his
residence. “We review de novo the district court’s legal determination of probable
cause.” United v. Hager, 

, 836 (8th Cir. 2013) (citing United States v.
Coleman, 

, 334 (8th Cir. 2012)).

      “Probable cause exists when there is a fair probability that contraband or
evidence of a crime will be found in a particular place.”

citations

in determining whether probable cause exists to issue a warrant.” 

                                          -6-
       The search warrant here was supported by probable cause. The warrant
application included an affidavit written by Special Agent Patricia J. Teakle of the
FBI, which carefully described PedoBook, the FBI’s methods of identifying its users,
and the link between DeFoggi and the website. As an initial matter, the affidavit
explained that because it was on the Tor network, PedoBook could not be accessed
without the installation of appropriate software and knowledge of its exact web
address. A user could obtain the web address for the website directly from other
users, or from internet postings describing PedoBook’s content and location, but not
from any type of web search. Accessing PedoBook therefore required numerous
affirmative steps by the user, making it extremely unlikely that a user would stumble
upon it without knowing that its purpose was to advertise and distribute child
pornography and understanding the content to be found there.

      The affidavit also explained that, through the government’s monitoring and
searches of the data logs once it had control of PedoBook, the FBI concluded that an
account was created on or about April 18, 2012, with the username “fuckchrist” and
display name “Ptasseater.” The affidavit included examples of activity conducted on
PedoBook by that member, including the filenames of the child pornography images
accessed and the private messages sent between that member and others. An FBI
“online covert employee” contacted that member via the private messaging feature
of PedoBook, and the member gave the FBI employee an email address
(fuckchrist@tormail.org) and told him he normally accessed the Tor network from
4:00 a.m. to 6:00 a.m. and 4:30 p.m. to 6:00 p.m.

      The affidavit then described how the FBI connected that username and display
name to DeFoggi. Several pages of the affidavit discussed how DeFoggi used these
same names for multiple child pornography websites, where he made comments very




                                         -7-
similar in substance and tone to those made on PedoBook. The FBI obtained an IP
address associated with the account “ptasseater” from one such website – an image
hosting website – which was connected to Verizon Internet Services. Verizon then
provided the personal information for the individual associated with that IP address
during the time period in which that user accessed child pornography on the image
hosting site – and that individual was DeFoggi. Other IP addresses used to access
child pornography were connected to DeFoggi in a similar manner.

         Moreover, the affidavit explained that a subject under FBI investigation for
activities related to child exploitation material had provided the FBI with information
on an individual initially identified as “Jeff,” who was a member of “boylover.net,”
a known website for underage male child pornography, and used a variety of email
addresses including “ptasseater@hotmail.com.” The informant also provided the FBI
with a cell phone number for “Jeff” and told them of an individual who had
personally met “Jeff.”

       “Jeff” turned out to be DeFoggi, and he told the individual (then under FBI
surveillance) in-person that his real name was Tim, that he worked in the DC area,
that he had a government security clearance, and that he had a domestic partner. An
open source database check confirmed that DeFoggi lived at 20311 Crown Ridge
Court, Germantown, Maryland. The FBI then confirmed through the United States
Postal Service and visual surveillance that DeFoggi received mail at that residence
and maintained a vehicle registered in his name there. The cell phone number for
“Jeff” was eventually linked to DeFoggi. Finally, through surveillance with a pen
register and a trap and trace obtained for DeFoggi’s internet account, the FBI learned
that computers in DeFoggi’s home were connected to the Tor network at the same
times that “ptasseater” claimed to be online in the private chats over PedoBook.




                                         -8-
        DeFoggi counters that because a Myspace profile included in the affidavit did
not belong to him, the FBI had failed to link him to the accounts with the usernames
“ptasseater” and “fuckchrist.” DeFoggi argues others could have used the same
usernames, and that because the affidavit did not identify an IP address for DeFoggi
that linked him directly to PedoBook (although the FBI connected IP addresses linked
to DeFoggi to other child pornography websites), there was no probable cause. Given
the cumulative information included in the search warrant application linking
DeFoggi to multiple child pornography websites including PedoBook, these
assertions do not detract from our conclusion that probable cause existed. The
affidavit in support of the search warrant provided more than enough information to
support a finding of probable cause to believe that evidence of criminal activity
would be found at DeFoggi’s residence.

      C.     Evidence of Chat Messages

       DeFoggi also argues that the district court erred in denying his motion to
exclude evidence of his “fantasy chat messages” at trial because they were not
relevant under Federal Rule of Evidence 401 and were unfairly prejudicial under
Federal Rule of Evidence 403. Challenges to evidentiary rulings are reviewed for an
abuse of discretion. United States v. Sewell, 

, 843 (8th Cir. 2006). We
will reverse only if an error “affects the substantial rights of the defendant” or has
“more than a slight influence on the [jury’s] verdict.” United States v. Yarrington,

, 447 (8th Cir. 2011) (quoting United States v. Elbert, 

, 775
(8th Cir. 2009)). “We will not reverse if the error was harmless.” 

states that to be relevant, evidence must tend to make a fact more or
less probable or “be of consequence in determining the action.” Fed. R. Evid. 401.
We have previously held that personal chats on child pornography websites are




                                         -9-
admissible as circumstantial evidence associating the defendant “with the child
pornography found on his computer,” and that “the district court was within its
discretion to admit” such chats. United States v. Manning, 

, 943 (8th
Cir. 2014). As in Manning, “portions of the chats contained identifying information
about [DeFoggi].” 

chats, DeFoggi wrote at length about his interest in
child pornography and solicited child pornography from other members of PedoBook.
DeFoggi’s chats therefore “revealed [his] identity, his preferences for different types
of child pornography, and his desire to exchange child pornography with other people
online.” 

DeFoggi was charged with knowingly accessing a means or
facility of interstate commerce to view child pornography, and the chats were relevant
(once DeFoggi was connected to his usernames) as a means of identifying DeFoggi
as the person knowingly accessing the child pornography on his computer. The
district court thus did not abuse its discretion in determining that DeFoggi’s chats
were relevant evidence under Rule 401.

       DeFoggi argues that even if the chats were relevant, the district court
nonetheless erred in admitting them because they were unfairly prejudicial due to
their shocking nature. Relevant evidence may still be excluded if “its probative value
is substantially outweighed by a danger of . . . unfair prejudice.” Fed. R. Evid. 403.
And we agree that chats fantasizing about raping and killing children “are by their
very nature disturbing,” and “highly likely to generate an emotional response.”
United States v. Evans, 

, 946 (8th Cir. 2015). But the disturbing nature
of otherwise relevant evidence cannot be the sole reason to exclude it. 

does not offer protection against evidence that is merely prejudicial in the sense
of being detrimental to a party’s case,” but rather “evidence that is ‘unfairly
prejudicial.’” (quoting United States v. McCourt, 

, 1092 (8th Cir.
2006))); see also United States v. Johnson, 

, 809 (8th Cir. 2006).




                                         -10-
       While the pure volume of the chats admitted into evidence concerns us, see

, DeFoggi makes only the most general of arguments on appeal
as to how their admission prejudiced him. He does not identify any specific chats he
believes are especially problematic; and he does not explain how the jury was
prejudiced, how the chats may have unfairly affected their view of the charges against
him, or how the chats were more disturbing than the images themselves. DeFoggi
calls the chats “shocking,” but “does not articulate what unfair prejudice resulted
from the publication of this evidence to the jury.” 

468 F.3d at
1092, for the proposition that “[t]he Supreme Court has advised that Rule 403
requires a preliminary showing of unfair prejudice before the need to balance the
probative value of the evidence and its alternatives arises”). Simply characterizing
the evidence in this way does not give us sufficient grounds to conclude that the
district court abused its discretion in admitting the chats.2 “Without a preliminary
showing of prejudice, ‘we need not consider or weigh the probative value’” of the
chats. 

States v. Worthey, 

, 1115 (8th Cir. 2013)).

      D.     Sufficiency of the Evidence

        DeFoggi alleges that the government failed to adduce sufficient evidence to
convict him beyond a reasonable doubt of a child exploitation enterprise and access
with intent to view child pornography. We review the sufficiency of the evidence in
a jury trial de novo, but examine the evidence in the light most favorable to the jury’s
verdict, resolving factual disputes and accepting all reasonable inferences in support
of the verdict. 

. We must uphold the jury’s verdict “if there
is an interpretation of the evidence that would allow a reasonable-minded jury to

      2
       DeFoggi repeats his assertion that his chat messages were overly prejudicial
with regard to his motion for a new trial. We reject his challenge to the denial of his
motion for a new trial based on his chat messages for these same reasons.



                                         -11-
conclude guilt beyond a reasonable doubt.” United States v. Thompson, 

, 733 (8th Cir. 2002).

             1.     Count 1

       DeFoggi was convicted of engaging in a child exploitation enterprise (CEE),
in violation of 18 U.S.C. § 2252A(g). Section 2252A(g) provides:

      (1) Whoever engages in a child exploitation enterprise shall be fined
      under this title and imprisoned for any term of years not less than 20 or
      for life.

      (2) A person engages in a child exploitation enterprise for the purposes
      of this section if the person violates [certain other sections] as a part of
      a series of felony violations constituting three or more separate incidents
      and involving more than one victim,3 and commits those offenses in
      concert with three or more other persons.

DeFoggi argues that under the proper application of the term “in concert with,” the
government provided insufficient evidence for the jury to convict him of engaging in
a CEE based on the predicate counts of accessing child pornography. We decide this
issue on narrow grounds. The indictment alleged that DeFoggi committed four
separate predicate violations as defined in § 2252A(g). Specifically, the government
charged four instances of accessing with intent to view child pornography in violation
of 18 U.S.C. § 2252A(a)(5)(b) (Counts 4–7). Section 2252A(a)(5)(b) is violated if
a person “knowingly accesses with intent to view, any . . . computer disk, or any other


      3
       The parties do not dispute that the CEE offense as charged involved more than
one victim.




                                         -12-
material that contains an image of child pornography that has been . . . shipped or
transported using any means or facility of interstate or foreign commerce or in or
affecting interstate or foreign commerce by any means, including by computer.”

        To convict DeFoggi of a CEE, there must be evidence that he committed at
least three of the predicate offenses “in concert with” three or more people.
Precedential guidance on the “in concert” language in the CEE offense is limited, but
in construing 21 U.S.C. § 848(c), which proscribes a criminal drug enterprise, the
Supreme Court has stated that “the plain meaning of the phrase ‘in concert’ signifies
mutual agreement in a common plan or enterprise” sufficient to constitute a
conspiracy. Rutledge v. United States, 

, 300 (1996). We agree with our
sister circuits that the Supreme Court’s construction of 21 U.S.C. § 848 informs our
reading of § 2252A(g). See United States v. Grovo, Nos. 15-30016, 15-30027, 

, at *4 (9th Cir. Jun. 23, 2016); United States v. Daniels, 

,
413 (6th Cir. 2011); United States v. Wayerski, 

, 1351 (11th Cir. 2010).
It follows from Rutledge’s holding that to act “in concert with” requires the same
mens rea as a conspiracy charge. Grovo, 

, at *4.

     In this case, however, we do not see sufficient evidence that DeFoggi
committed the predicate offenses of accessing child pornography “in concert with”
anyone else – even assuming for purposes of analysis that “in concert with” means
no more than an agreement.4 For each predicate count, the jury was presented with


      4
       While DeFoggi argues, as others before him have done, that the statute
requires each individual predicate felony to be committed “in concert with” three
other persons, we agree with the Ninth and Sixth Circuits that “the more natural
reading of § 2252A(g) is that ‘the required total of three other persons may be tallied
by considering the predicate counts together.’” Grovo, 

, at *5
(quoting 

).



                                         -13-
screenshots of other members’ profiles and the images DeFoggi clicked on that were
uploaded to the profiles. But we do not understand how the single act of accessing
an image with the intent to view it by clicking on it alone from behind one’s computer
screen can be done “in concert with” anyone else – at least not on the facts presented
here. The government argues that DeFoggi entered a “conspiracy” with three or more
other people “to commit the offense of accessing with intent to view child
pornography.”5 But even assuming without deciding that the CEE offense requires
a conspiracy and nothing more, the evidence was insufficient here. Conspiracy
requires an agreement to accomplish the specific illegal objective at issue – here,
accessing child pornography. The evidence showed that many people voluntarily
joined PedoBook in part to access child pornography. But that does not necessarily
mean that DeFoggi, when he accessed child pornography on the specific occasions
charged in the predicate counts 4–7, agreed to do so with anyone else. And the trial
record is bereft of evidence of any such agreement in this case. Even if we further
assume that participants in the enterprise need not act simultaneously, see 

the government failed to offer evidence that DeFoggi acted in concert with anyone
concerning the underlying elements of the offense of accessing with intent to view
child pornography as charged in Counts 4–7.




      5
       We note that this argument appears to overlook the statutory requirement that
a person charged with engaging in a CEE must commit three offenses, not simply
agree to commit them, in order to be convicted. See 18 U.S.C. § 2252A(g).



                                        -14-
       Like several of the defendants in the cases analyzed by our sister circuits,6
DeFoggi participated in interactive features of the child pornography website at issue,
such as private messaging between members. Yet that conduct is separate and apart
from the offenses that constituted the underlying predicates necessary to sustain the
child exploitation enterprise offense, i.e., accessing with intent to view child
pornography. Whether or not DeFoggi’s other PedoBook-related activities were
proscribed by other statutes, the government failed to prove that DeFoggi was guilty
of violation 18 U.S.C. § 2252A(g) as the offense was charged in this case.

              2.     Counts 4–7

       DeFoggi also argues that no reasonable jury could have concluded beyond a
reasonable doubt that he “intentionally” accessed PedoBook to view child
pornography as charged in Counts 4–7. This is because, he asserts, (1) the
government failed to provide any direct evidence that he was the person who was
using the computer to view PedoBook, (2) even if he did access PedoBook, he did so
because he used the Tor network for work, not so that he could view child
pornography, and (3) his chats did not show an intent to access or solicit child
pornography because they were “mere fantasy.”7


      6
        See, e.g., Grovo,

of times, . . . gained admission to the upper level of the . . . board after being admitted
and elevated through a vouching process, . . . [and] repeatedly accessed and
distributed child pornography.”); 

(defendants participated
in a sophisticated group, communicated with each other, limited its membership, and
“made specific requests for and purchased the production of new illicit material”).

        DeFoggi also makes these assertions in support of his argument that there was
insufficient evidence to convict him on Count 1. Given our ruling above, we consider
them only as to Counts 4–7.



                                           -15-
       As previously discussed, evidence tied DeFoggi to the online username and
display name “fuckchrist” and “Ptasseater” on the PedoBook website. The FBI’s
investigation into those usernames through open source database searches,
administrative subpoenas to DeFoggi’s internet service providers, and cooperation
with foreign law enforcement revealed that the usernames belonged to DeFoggi.
There was Tor traffic associated with those identities occurring at his residence in the
early morning hours on the PedoBook website. In private chats on PedoBook,
DeFoggi disclosed identifying information such as his geographic location and the
times when he frequented PedoBook and other child pornography websites. His in-
person meeting with another person under investigation established that his name was
Tim and let the FBI know DeFoggi had a domestic partner who was unaware of his
interests (information that eventually helped the FBI determine who at DeFoggi’s
address was accessing child pornography). DeFoggi had extensive knowledge of the
Tor network, and PedoBook could not be discovered and accessed without it. The
jury was reasonable in concluding that DeFoggi was accessing PedoBook.

       Moreover, it was reasonable for the jury to conclude that DeFoggi accessed
PedoBook with the intent to view child pornography. The fantasy chat messages on
PedoBook revealed “copious amounts of discussion concerning the exchange of child
pornography with other users.” 

. DeFoggi disclosed
identifying details about himself “in the context of discussing the exchange of child
pornography with others.” 

that those chats were “mere fantasy”
and not indicative of solicitation or of a step toward obtaining child pornography. He
argues that the chats are therefore “speech protected under the First Amendment.”
However, the solicitation of child pornography can be proscribed without First
Amendment concerns where a “statute penalizes speech that accompanies or seeks
to induce a transfer of child pornography – via reproduction or physical delivery –
from one person to another.” United States v. Williams, 

, 294 (2008).




                                         -16-
“[O]ffers to provide or requests to obtain child pornography are categorically
excluded from the First Amendment.” 

DeFoggi asked other members of
PedoBook where he could find certain videos and whether they had or could produce
images for him. He then provided his email address to those other members. Such
solicitations were not just “speech protected under the First Amendment,” as DeFoggi
argues. Rather, the evidence presented at trial was sufficient to prove that he
intended to access child pornography.

       Additional evidence also showed that DeFoggi was accessing PedoBook and
illustrated his specific intent to access child pornography in doing so. For instance,
when the FBI executed the search warrant at DeFoggi’s residence, he had to be
forcibly separated from his laptop, which was actively downloading a child
pornography video. The laptop contained evidence of the username “fuckchrist” and
a Yahoo Messenger profile for “PTasseater69.” In addition, the Tor browser bundle
was found on the laptop with evidence of browsing activities on multiple child
pornography sites, including PedoBook. Images of child pornography were also
located on the computer. DeFoggi’s actions in attempting to maintain anonymity by
creating usernames, registering as a member of the website, creating a profile page,
selecting or accepting other members as “friends,” joining various subcategory
groups, requesting or soliciting child pornography from other members, as well as the
contents of his laptop when he was apprehended are more than enough to support a
jury finding of intent.

       The jury was free to accept or reject DeFoggi’s theory that someone else had
used his computer or that he had accessed PedoBook for professional reasons. See
United States v. Henley, 

, 905 (8th Cir. 2014) (“In reviewing a challenge
to the sufficiency of the evidence . . . ‘a jury’s credibility determinations are virtually
unreviewable.’” (quoting United States v. Perez, 

, 391 (8th Cir. 2011))).




                                           -17-
He does no more than restate that argument here. Upon the evidence presented, we
find that a reasonable jury could conclude beyond a reasonable doubt that DeFoggi
accessed PedoBook and other websites with the intent to view child pornography.

       The offense of accessing child pornography also requires an “interstate
commerce” nexus.8 DeFoggi alleges that there is no evidence that the computer disk
or other material containing visual depictions of child pornography were transported
in interstate commerce because “[t]he interstate nexus must be established prior to the
user’s access.” “The Internet is an instrumentality and channel of interstate
commerce.” United States v. Havlik, 

, 824 (8th Cir. 2013) (citing
United States v. Trotter, 

, 921 (8th Cir. 2007)). DeFoggi’s use of the
internet to access and download images and videos from PedoBook is enough in this
case to satisfy the interstate commerce nexus. Even if it were not, the content of
PedoBook was uploaded by the website’s global users. The server that hosted the
data that comprised the PedoBook website was located in Nebraska. A user accessing
the website and its content from Maryland would be accessing data that was stored
on and had traveled from a server located in Nebraska. A reasonable trier of fact
therefore could find that DeFoggi accessed the website with the intent to view child

Instructions10

        DeFoggi challenges Instruction 37, which begins with the sentence “You have
heard evidence that the defendant committed offenses involving child pornography
that were not charged in the Indictment.” DeFoggi argues that the sentence should
have read: “You have heard evidence that the defendant committed similar acts in the
past that were not charged in the Indictment.” But DeFoggi himself requested an
instruction that included the language he now objects to, and his objection is therefore
waived. See United States v. Davis, 

, at *3 (8th Cir. Jun. 24, 2016)
(“When a party expressly agrees to an instruction, the doctrine of invited error
applies, and any objection to the instruction is waived.” (citations omitted)). Even
if this issue were properly before us, DeFoggi fails to offer any argument as to why
the objected-to language is erroneous. See United States v. Byrd, 

,
1029 (8th Cir. 1976) (citing United States v. Phillips, 

, 391 (8th Cir.
1975)); see also Ahlberg v. Chrysler Corp., 

, 634 (8th Cir. 2007)

       DeFoggi alleged that because the evidence was insufficient the district court
abused its discretion in denying his motion for a new trial. As discussed in our
analysis of DeFoggi’s challenge to the sufficiency of the evidence, the evidence
adequately supported the jury’s verdict on all but DeFoggi’s conviction for a child
exploitation enterprise.
      10
        DeFoggi asserts various errors in the jury instructions as they relate to Count
1, including the definition of the phrase “in concert with.” He also reasserts other
objections to the instructions as they relate to Count 1. Given our ruling above, we
need not address these arguments.

, 725 (8th Cir. 2009) (“The district court has wide
discretion in formulating instructions.” (quoting United States v. Long,

instruction, but offers no argument as to why or how the district court erred, so this
objection is likewise waived. See

                                  III. Conclusion

      Because DeFoggi was improperly convicted of engaging in a child exploitation
enterprise, we vacate his conviction and remand for resentencing.11 We affirm the
judgments in all other respects.
                       ______________________________




      11
        DeFoggi contends that the 20-year mandatory minimum sentence for a child
exploitation enterprise is a violation of the Eighth Amendment’s ban on cruel and
unusual punishment. As we vacate his conviction on that count, we need not address
DeFoggi’s Eighth Amendment challenge.
