MEMORANDUM **

James Leroy Carter appeals from the district court’s judgment and challenges his guilty-plea conviction for failure to register and update his sex offender registration under the Sex Offender Registration and Notification Act (“SORNA”), in violation of 18 U.S.C. § 2250(a). We have jurisdiction under 28 U.S.C. § 1291. We review Carter’s challenge to the district court’s denial of his motion to dismiss the indictment de novo, see United States v. Cabrera-Gutierrez, 756 F.3d 1125, 1129 (9th Cir. 2014), cert. denied, — U.S. -, 135 S.Ct. 124, — L.Ed.2d - (2014), and we affirm.

Carter contends that Congress violated the non-delegation doctrine because it allows the Attorney General authority to legislate SORNA’s retroactive application. This contention is foreclosed. See United States v. Richardson, 754 F.3d 1143, 1146 (9th Cir. 2014) (per curiam) (“SORNA’s delegation of authority to the Attorney General to determine the applicability of SORNA’s registration requirements to pre-SORNA sex offenders is consistent with the requirements of the non-delegation doctrine.”).

AFFIRMED.
