LEONARD T. STRAND, District Judge.
This matter is before me on a Report and Recommendation (R&R) in which the Honorable Jon Stuart Scoles, Chief United States Magistrate Judge, recommends that I accept defendant's plea of guilty. See Doc. No. 31.
On February 3, 2016, defendant was charged in a three-count indictment with charges related to child pornography. Count 1 charged defendant with distribution of child pornography in violation of 18 U.S.C. §§ 2252(a)(2) and 2252(b)(1). Count 2 charged defendant with receipt of child pornography in violation of 18 U.S.C. §§ 2252(a)(2) and 2252(b)(1). Count 3 charged defendant with possession of child pornography in violation of 18 U.S.C. §§ 2252(a)(5)(B) and 2252A(b)(1). On April 6, 2016, defendant appeared before Judge Scoles and changed his plea to guilty with regard to Count 2. On that same date, Judge Scoles filed an R&R in which he recommends that defendant's guilty plea be accepted. The parties have not filed written objections to the R&R and any objections are now deemed waived. See N.D. Ia. L.R. 72.1.
A district judge must review a magistrate judge's R&R under the following standards:
28 U.S.C. § 636(b)(1); see also Fed. R. Civ. P. 72(b). Thus, when a party objects to any portion of an R&R, the district judge must undertake a de novo review of that portion.
Any portions of an R&R to which no objections have been made must be reviewed under at least a "clearly erroneous" standard. See, e.g., Grinder v. Gammon, 73 F.3d 793, 795 (8th Cir. 1996) (noting that when no objections are filed "[the district court judge] would only have to review the findings of the magistrate judge for clear error"). As the Supreme Court has explained, "[a] finding is `clearly erroneous' when although there is evidence to support it, the reviewing court on the entire evidence is left with the definite and firm conviction that a mistake has been committed." Anderson v. City of Bessemer City, 470 U.S. 564, 573-74 (1985) (quoting United States v. U.S. Gypsum Co., 333 U.S. 364, 395 (1948)). However, a district judge may elect to review an R&R under a more-exacting standard even if no objections are filed:
Thomas v. Arn, 474 U.S. 140, 150 (1985).
Because neither party objected to the R&R, I have reviewed it for clear error. Based on that review, I am not "left with the definite and firm conviction that a mistake has been committed." Anderson, 470 U.S. at 573-74. As such, I hereby
