Carl Lucas pleaded guilty to violating 18 U.S.C § 2250(a) based on his failure to register as a sex offender pursuant to the Sex Offender Registration and Notification Act (SORNA), 42 U.S.C. §§ 16901-16991. The district court 1 sentenced Lucas to a term of twenty-eight months in prison, with ten years of supervised release to follow. Lucas entered a conditional plea which preserved his right to bring this appeal.

*691 In the present appeal, Lucas argues SORNA violates the (1) Due Process Clause; (2) Ex Post Facto Clause; (3) the constitutional doctrine of non-delegation; (4) the notice and comment requirements of the Administrative Procedure Act (APA), 5 U.S.C. § 553; and (5) the Commerce Clause of the U.S. Constitution. Because the issues presented before this court involve “either statutory interpretation of SORNA or constitutional challenges to SORNA’s applicability,” we review each issue de novo. United States v. May, 535 F.3d 912, 915 (8th Cir. 2008).

We are bound by our prior precedent, and reject each of Lucas’s challenges. See May, 535 F.3d at 921 (rejecting a claim SORNA violates the Due Process Clause when defendant has prior notice of state registration requirements); United States v. Waddle, 612 F.3d 1027, 1029 (8th Cir. 2010) (concluding SORNA does not violate the Ex Post Facto Clause); United States v. Zuniga, 579 F.3d 845, 850-51 (8th Cir. 2009) (concluding defendant had no standing to bring non-delegation doctrine challenge because § 16913(d) does not apply to defendants who were required to register prior to enactment of SORNA); United States v. Hacker, 565 F.3d 522, 528 (8th Cir. 2009) (concluding defendant had no standing to raise APA challenge to SOR-NA); United States v. Howell, 552 F.3d 709, 717 (8th Cir. 2009) (concluding SORNA is constitutionally authorized under the Commerce Clause and the Necessary and Proper Clause).

We therefore affirm the judgment of the district court.
