A jury convicted Francisco RomeroPina of possession of a firearm by a prohibited person, immigration fraud, and identification document fraud, in violation of 18 U.S.C. §§ 922(g)(5), 1546(a), and *36 1028(a)(1), respectively. 1 The district court sentenced Romero-Pina to a term of 42 months of imprisonment to be followed by a two-year term of supervised release. Romero-Pina now appeals his conviction on several grounds. Finding no error, we affirm.

Romero-Pina first argues that the district court erred by denying his suppression motion. Specifically, Romero-Pina sought to suppress (1) evidence obtained during a search of the apartment in which he and his friend resided, and (2) certain statements he made to law enforcement. Following a suppression hearing, a magistrate judge found that Romero-Pina and his friend voluntarily consented to the search of their apartment. The magistrate judge further found that RomeroPina’s statements were “probably” made during a non-custodial interview, and they were in any event made after he had knowingly and voluntarily waived his Miranda rights. On de novo review, the district court overruled Romero-Pina’s objections and sustained these -findings. 2 In considering this issue, we review the district court’s factual findings for clear error, viewing the evidence in the light most favorable to the government, and we review the district court’s legal conclusions de novo. See United States v. Perkins, 363 F.3d 317, 320 (4th Cir. 2004). Applying these standards, we find that the district court did not err by denying the suppression motion. 3

Romero-Pina next argues that the district court erred by denying his motion to enforce an alleged agreement made by a law enforcement agent not to prosecute him. Romero-Pina bore the burden of proving that such an agreement existed and that it was binding on the government. See United States v. Martin, 25 F.3d 211, 217 (4th Cir. 1994) (noting burden of proof concerning plea agreements). We review the district court’s factual determinations concerning the existence and scope of an alleged immunity agreement under a clearly erroneous standard, and its application of the law de novo. See id. Having carefully reviewed the record, we find that the district court did not err in denying this motion.

Romero-Pina also argues that the district court erred by denying his Second Amendment challenge to § 922(g)(5). We have reviewed this constitutional issue de novo, see United States v. Bostic, 168 F.3d 718, 721 (4th Cir. 1999), and find that Romero-Pina’s argument is foreclosed by our decision in United States v. Johnson, 497 F.2d 548, 550 (4th Cir. 1974), in which we rejected a similar Second Amendment challenge to § 922(g).

*37 Finally, Romero-Pina argues that the district court erred by declining to give his proposed jury instruction concerning the interstate commerce element for the § 922(g)(5) charge. We review de novo the correctness of jury charges regarding the elements of an offense. United States v. Horton, 321 F.3d 476, 479 (4th Cir. 2003). Because the district court’s instruction properly comports with our circuit precedent, see, e.g., United States v. Quarles, 330 F.3d 650, 651 n. 1 (4th Cir. 2003) (rejecting a similar argument), 4 we find that the district court did not err by declining to give Romero-Pina’s requested instruction.

We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.
