LEONARD T. STRAND, District Judge.
This matter is before me on a Report and Recommendation (R&R) in which the Honorable C.J. Williams, United States Magistrate Judge, recommends that I accept defendant's plea of guilty. See Doc. No. 57.
On April 20, 2016, defendant was charged in Counts 1 and 2 of a four-count indictment (Doc. No. 3). Count 1 charges defendant with conspiracy to distribute a controlled substance in violation of 21 U.S.C. §§ 841(a)(1), 841(b)(1)(A) and 846. Count 2 charges defendant with possession with intent to distribute a controlled substance in violation of 18 U.S.C. § 2, 21 U.S.C. §§ 841(a)(1) and 841 (b)(1)(A). On August 24, 2016, defendant appeared before Judge Williams and changed his plea to guilty with regard to Count 1. Judge Williams filed the R&R on the same date. The parties have waived the right to object to the R&R and have consented to its acceptance. See Doc. No. 58.
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 objects 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
