RENDELL, Circuit Judge:

                                   I. BACKGROUND

        For nearly three years, Dr. William O’Brien prescribed large quantities of

medically-unnecessary oxycodone, methadone, and alprazolam to individuals in

exchange for cash and sexual favors. 1 In 2013, O’Brien prescribed 120 oxycodone pills

and sixty methadone pills for one of his “patients”, Joseph Ennis. Supp. App. 986, 997-

98. Five days later, Ennis was discovered dead in his apartment, with high levels of

oxycodone, methadone, and a third drug, cyclobenzaprine, in his blood. 2 Supp. App.

1321.

        O’Brien was subsequently charged with two counts of conspiracy to dispense and

distribute a controlled substance (21 U.S.C. § 846), 114 counts of distributing a Schedule

II controlled substance (21 U.S.C. § 841(a)(1), (b)(1)(C)), seven counts of distributing a

Schedule IV controlled substance (21 U.S.C. § 841(a)(1), (b)(1)(E)), one count of

dispensing a controlled substance that resulted in death (21 U.S.C. § 841(a)(1),

(b)(1)(C)), one count of conspiracy to engage in money laundering (18 U.S.C. § 1956(h)),

  Oxycodone and methadone are Schedule II opioid-based controlled substances. 21
C.F.R. § 1308.12(c). Alprazolam, typically referred to by its brand-name, Xanex, is a
Schedule IV controlled substance. 21 C.F.R. § 1308.14(c).

  O’Brien had not prescribed cyclobenzaprine for Ennis. Supp. App. 1321.

one count of conspiracy to commit bankruptcy fraud (18 U.S.C. § 371), and one count of

making a false oath in bankruptcy proceedings (18 U.S.C. § 152(2)).

       At a pre-trial hearing on the government’s motion to remove O’Brien’s privately-

retained counsel due to a conflict of interest, O’Brien told the court that he intended to

fire his counsel and proceed pro se. Supp. App. 4. The District Court strongly advised

him not to do so, but O’Brien maintained that he “would like to exercise [his] 6th

Amendment rights.” Supp. App. 4. The District Court heard argument on, and ultimately

granted, the government’s motion to remove O’Brien’s conflicted counsel. Supp. App.

20.

       The District Court held a hearing on O’Brien’s oral motion to proceed pro se.

Supp. App. 27. Prior to the hearing, the government filed a motion asking the District

Court to appoint counsel to advise O’Brien on his request to proceed pro se. Supp. App.

1387-90. O’Brien opposed the government’s request and again asserted his right to

proceed pro se. Supp. App. 1387-90. The District Court did not appoint O’Brien counsel.

At the beginning of the hearing, the government asked the District Court to appoint

O’Brien counsel to represent him at the hearing. Supp. App. 29. The District Court

denied the government’s request and proceeded with a Peppers colloquy. 3 Supp. App.

35. O’Brien answered all the District Court’s questions and repeatedly stated that he

understood the law and the implications of proceeding pro se. Supp. App. 29-45. The

District Court concluded that O’Brien had knowingly and voluntarily waived his right to

 In United States v. Peppers, 

(3d Cir. 2002), we provided a list of fourteen
questions intended to guide courts in determining whether a defendant’s decision to
proceed pro se is knowing, intelligent, and voluntary.

counsel, granted his request to represent himself, and appointed an attorney as standby

counsel. Supp. App. 48.

      O’Brien proceeded to trial. A parade of witnesses, a confidential informant,

videotape evidence, and expert testimony indicated that O’Brien had prescribed

oxycodone and methadone to numerous individuals, including Joseph Ennis, outside the

usual course of professional practice and for no medical purpose. Supp. App. 768, 791,

935-36, 938, 942-47, 1146, 1127-28. Two medical experts testified that Ennis had died

from a combination of oxycodone and methadone. Supp. App. 1291, 1294, 1355, 1379.

Although they disagreed on the exact role played by the third drug, cyclobenzaprine, they

agreed that, absent the oxycodone and methadone, Ennis would not have died. 4

      Peter Marrandino, a cooperating codefendant and O’Brien’s former patient,

testified on behalf of the government. O’Brien’s cross-examination of Marrandino lasted

two days. On the first day, O’Brien questioned Marrandino about the possibility that, in

exchange for his testimony against O’Brien, Marrandino could receive a lighter sentence.

Supp. App. 251-52. Marrandino answered O’Brien’s questions willingly and testified

that he indeed hoped to receive a lighter sentence in exchange for his cooperation. 

second day of cross-examination, O’Brien asked Marrandino several questions about

his plea agreement, which said that the government would file a “5K” in Marrandino’s




4
 Dr. Stephen Thomas testified that cyclobenzaprine did not contribute at all to Ennis’s
death. Supp. App. 991, 1283-84, 1288. Dr. Ian Hood testified that the cyclobenzaprine
may have contributed to Ennis’s death but that, absent the methadone and oxycodone,
cyclobenzaprine would not have caused Ennis’s death. Supp. App. 1379.

case in exchange for his testimony. 5 Supp App. 345-46. When Marrandino indicated that

he did not understand the technicalities of the 5K process, the District Court stepped in to

explain the 5K motion process to the jury. Supp. App. 347. The District Court then said

“that’s as much as we are going to go into the 5K1.1 motion.” Supp. App. 347. O’Brien

did not ask Marrandino any additional questions about his plea agreement or his

expectation of a reduced sentence.

       Angela Rongione, another cooperating codefendant and O’Brien’s former office

manager, also testified on behalf of the government. At two separate points during cross-

examination, O’Brien questioned Rongione about her expectation of a reduced sentence

in exchange for her testimony. Supp. App. 545, 627-28. When O’Brien attempted to

broach the subject a third time, the District Court sustained the government’s objection

on the grounds that Rongione had already testified on that issue. Supp. App. 743.

O’Brien asked Rongione one more time if she was testifying in order to receive a reduced

sentence, then pursued no further questions on the topic. Supp. App. 743.

       After the close of evidence, the District Court instructed the jury. It gave the

following instruction on the charge of dispensing a controlled substance resulting in death

under 21 U.S.C. § 841(b)(1)(C):

                     To find the defendant guilty of distributing or
              dispensing oxycodone or methadone outside of the usual
              course of professional practice and not for a legitimate
              medical purpose that results in death, you must find that the

  Under § 5K1.1 of the United States Sentencing Guidelines, the government may motion
a sentencing court to depart from the guidelines and impose a reduced sentence on a
defendant who has provided substantial assistance in the investigation or prosecution of
another person who has committed an offense.
                                              5
              government has proved beyond a reasonable doubt each of
              the elements of distribution or dispensing of a controlled
              substance outside the usual course of professional practice
              and not for a legitimate medical purpose, which I have just
              explained to you.
                      In addition to these elements, you must also find that
              the government has proved beyond a reasonable doubt that
              oxycodone and methadone distributed by the defendant
              resulted in the death of another, specifically, Joseph Ennis.
                      In order to establish that these controlled substances
              were distributed or dispensed by the defendant [and] resulted
              in the death of Joseph Ennis, the government must prove that
              Joseph Ennis died as a consequence of his use of oxycodone
              and methadone that the defendant distributed or dispensed on
              or about the date alleged in the indictment.
                      The law provides that . . . death is a consequence of a
              victim’s use of [a] controlled substance that was distributed or
              dispensed by the defendant, a more serious offense is
              committed regardless of whether the defendant knew or
              should have known that death [would] result.
                      There is no requirement that death resulting from the
              use of [a] controlled substance was a reasonably foreseeable
              event or that the controlled substance was a proximal cause of
              the death. A finding by you that[,] but for the victim’s
              ingesting of the charged controlled substance, distributed or
              dispensed . . . by the defendant, the victim would not have
              died[,] satisfies the standard.
                      The fact that Joseph Ennis may have used other drugs
              in addition to oxycodone and methadone is not relevant if you
              determine that he would not have died without ingesting these
              two substances, the oxycodone and the methadone. That is,
              the defendant cannot be found guilty absent evidence that the
              victim would have lived but for [the] oxycodone and
              methadone used which were prescribed by the defendant.
              Supp. App. 1383-85.

The jury found O’Brien guilty of all counts except four of the distribution counts. App. 2.

                                      II. ANALYSIS

    A. District Court’s Failure to Appoint Counsel for O’Brien’s Peppers Hearing

       First, O’Brien argues that the District Court’s failure to appoint counsel to

represent him at his Peppers hearing violated his Sixth Amendment right to counsel.

Because this issue was not raised before the District Court, we review for plain error. See

Fed. R. Crim. P. 52. 6 A defendant establishes plain error by proving that the court erred,

that the error was obvious under the law at the time of review, and that the error affected

the outcome of the proceedings. Johnson v. United States, 

, 467 (1997).

       O’Brien does not take issue with the District Court’s Peppers colloquy or its

subsequent conclusion that his waiver of counsel was knowing and voluntary. Instead, he

challenges the District Court’s failure to appoint counsel to represent him at the Peppers

hearing itself. However, O’Brien has not identified, nor have we found, any legal

authority supporting the proposition that a defendant must be represented by counsel at a

hearing to waive the right to counsel. Thus, even if the District Court’s refusal to appoint

counsel to represent O’Brien at his Peppers hearing was erroneous, that error is not

“obvious” under current law, as required under the plain error standard. 

. Thus, O’Brien is not entitled to relief based on this issue.

6
  Appellees argue that O’Brien waived his Sixth Amendment right to counsel by
repeatedly and explicitly asserting his right to proceed pro se, opposing the government’s
request to appoint counsel, and rejecting the District Court’s offer to allow him to consult
with counsel. See United States ex rel. O’Connor v. State of New Jersey, 

,
634 n.2 (3d Cir. 1969) (“The Supreme Court has defined waiver as ‘an intentional
relinquishment or abandonment of a known right or privilege.’” (quoting Johnson v.
Zerbst, 

, 464 (1938))). However, we assume for purposes of this appeal that
O’Brien has not waived his Sixth Amendment claim.

                                              7
                 B. Cross-Examination of Marrandino and Rongione

       Next, O’Brien argues that the District Court erred in curtailing his cross-

examination of Marrandino and Rongione regarding their expectations of reduced

sentences in exchange for their testimony. We review a District Court’s limitation on

cross-examination of witnesses for abuse of discretion, United States v. Ellis, 

, 498 (3d Cir. 1998), and we will only reverse if the limitation “is so severe as to

constitute a denial of the defendant’s right to confront witnesses against him and it is

prejudicial to the substantial rights of the defendant,” United States v. Friedman, 

, 352 (3d Cir. 2011) (quoting United States v. Casoni, 

, 918-19 (3d

Cir. 1991)).

       A criminal defendant “states a violation of the Confrontation Clause by showing

that he was prohibited from engaging in otherwise appropriate cross-examination

designed to show a prototypical form of bias on the part of the witness[.]” Delaware v.

Van Arsdall, 

, 680 (1986). Inquiring into a cooperating defendant’s

expectations for leniency is appropriate, as potential leniency in exchange for testimony

provides a witness “a motive for favoring the prosecution in his testimony.” 

However, even if a court errs in limiting a defendant’s ability to question a witness

regarding his or her expectations of leniency, the error is harmless unless a reasonable

jury would have received a significantly different impression of the witness if the

defendant had been permitted to pursue his proposed line of inquiry. See United States v.

Chandler, 

, 221 (3d Cir. 2003) (citing Van 

).



                                              8
       O’Brien argues that his right to cross-examine Marrandino was violated when the

District Court foreclosed further discussion of the 5K process. However, any error the

District Court may have committed by limiting further questioning on this subject was

harmless. O’Brien had already questioned Marrandino about his hope of leniency in

exchange for his testimony. Marrandino had answered those questions willingly, and the

jury was given an adequate opportunity to evaluate his credibility in light of his potential

bias. A reasonable jury would not have received a significantly different impression of

Marrandino if O’Brien had been permitted to ask him additional questions about the

details of his plea agreement or the 5K motion process.

       O’Brien argues that his right to cross-examine Rongione was violated when the

District Court sustained the government’s objection to questions regarding Rongione’s

hope for a reduced sentence in exchange for her testimony. However, O’Brien had been

permitted to question Rongione on this issue twice before the District Court sustained the

government’s objection to further questioning. Further interrogation would have been

repetitive, and a reasonable jury would not have received a significantly different

impression of Rongione if O’Brien had been permitted to ask those questions a third

time. Therefore, the District Court’s limitation of O’Brien’s opportunity to cross-examine

Marrandino and Rongione was harmless.

                                   C. Jury Instruction

       At the charging conference, O’Brien’s standby counsel raised four objections to

the proposed jury instruction on the charge of dispensing a controlled substance resulting

in death under 21 U.S.C. § 841(b)(1)(C). Supp. App. 1432-34. O’Brien raises the same

                                             9
four issues on appeal. We review jury instructions de novo to determine whether, if taken

as a whole, they properly appraised the jury of the issues and the applicable law. Gutzan

v. Altair Airlines, Inc., 

, 138 (3d Cir. 1985). Absent an affirmative

misstatement of the applicable law, our review is for an abuse of discretion. United States

v. Maury, 

, 261 (3d Cir. 2012).

       First, O’Brien argues that the jury should have been instructed that they could only

find him guilty if the controlled substance that caused Ennis’s death was taken “in

accordance with instructions by the prescribing physician.” Br. for Appellant at 21. A

defendant is guilty of violating 21 U.S.C. § 841(b)(1)(C) if he unlawfully distributes a

controlled substance and if “death or serious bodily injury results from the use of such

substance.” O’Brien has not provided, nor can we find, any legal support for the notion

that a physician who illegally prescribes a controlled substance is only guilty for a death

that results from the use of the controlled substance if the victim ingested it in accordance

with the instructions that accompanied the illegitimate prescription. Thus the jury

instruction accurately stated the applicable law. 7




7
  O’Brien also suggests that this additional instruction was necessary because Ennis may
have obtained methadone and oxycodone from a source other than O’Brien. However, the
jury instructions made clear that, in order to find O’Brien guilty of distribution of a
controlled substance resulting in death, the jury had to find that the controlled substance
distributed by O’Brien was the cause of Ennis’s death. See Supp. App. 1384 (“You must
also find that the government has proved beyond a reasonable doubt that oxycodone and
methadone distributed by the defendant results in the death of another, specifically,
Joseph Ennis. . . . [T]he government must prove that Joseph Ennis died as a consequence
of his use of oxycodone and methadone that the defendant distributed or dispensed on or
about the date alleged in the indictment.”).
                                              10
       Next, O’Brien argues that the following phrase was prejudicial: “The law provides

that whenever . . . death is a consequence of a victim’s use of a controlled substance that

was distributed or dispensed by the defendant, a more serious offense is committed.”

However, this is an accurate statement of the law: 21 U.S.C. § 841(b)(1)(C) prescribes an

enhanced penalty for distribution of a controlled substance when the distribution results

in death. See Burrage v. United States, 

, 892 (2014) (referring to 21 U.S.C.

§ 841(b)(1)(C) as a “penalty enhancement provision”). The District Court did not abuse

its discretion by clarifying for the jury the relationship between mere distribution of a

controlled substance and the more serious crime of distribution of a controlled substance

resulting in death.

       O’Brien also argues that the jury instruction should have defined the term

“proximal cause.” The District Court accurately explained the relevant causation standard

to the members of the jury: they did not need to find that the controlled substance was the

proximal cause of the victim’s death, simply that it was the but-for cause. Supp. App.

1384. This is an accurate statement of the law. See 

(a

defendant is guilty of violating the statute if the controlled substance was the but-for

cause of the victim’s death); United States v. Robinson, 

, 831 (3d Cir. 1999)

(the controlled substance need not be the proximate cause of the victim’s death). The

District Court did not abuse its discretion by declining O’Brien’s request to define a

complicated causation standard that was not relevant to the jury’s verdict. In fact, such a

definition may have unnecessarily confused the jury.



                                             11
       Finally, O’Brien takes issue with the following phrase: “The fact that Joseph Ennis

may have used other drugs in addition to oxycodone and methadone is not relevant[.]” He

argues that the presence of a third drug in Ennis’s system, cyclobenzaprine, was relevant

because Dr. Hood testified that an overdose of cyclobenzaprine could lead to death and

that Ennis had high levels of cyclobenzaprine in his system. Read in isolation, this phrase

appears problematic, as it suggests that O’Brien could be held responsible for Ennis’s

death even if his death was the result of a drug O’Brien had not prescribed. However, we

must evaluate the jury instructions as a whole. When read in conjunction with the rest of

the sentence, this phrase accurately states the applicable law:

                     The fact that Joseph Ennis may have used other drugs
              in addition to oxycodone and methadone is not relevant if you
              determine that he would not have died without ingesting these
              two substances, the oxycodone and the methadone. That is,
              the defendant cannot be found guilty absent evidence that the
              victim would have lived but for [the] oxycodone and
              methadone used which were prescribed by the defendant.
              Supp. App. 1385 (emphasis added).

Read as a whole, the jury instructions accurately informed the jury of the applicable law:

O’Brien could only be found guilty of violating 21 U.S.C. § 841(b)(1)(C) if the

oxycodone and methadone he unlawfully prescribed were the but-for cause of Ennis’s

death, even if Ennis took other drugs as well. Thus, O’Brien’s claim that the jury

instructions were erroneous fails.

                                      III. Conclusion

       For the foregoing reasons, we affirm the orders of the District Court.
