SUMMARY ORDER

Defendant-appellant Herman Gundy appeals his conviction and sentence, following a bench trial on stipulated facts, for one count of failing to register as a sex offender after traveling in interstate commerce, in violation of the Sex Offender Registration and Notification Act (“SORNA”), 18 U.S.C. § 2250(a). We assume the parties’ familiarity with the underlying facts and the procedural history of the case, to which we refer only as necessary to explain our decision to affirm.

While serving a federal sentence for violating' Maryland Criminal Law § 3-306, Sexual Offense in the Second Degree, during his supervised release for a prior federal offense, Gundy was transferred from Maryland to a federal prison in Pennsylvania. See United States v. Gundy, 804 F.3d 140, 143 (2d Cir. 2015). As he approached the end of his federal sentence, Gundy authorized the Department of Justice to make arrangements for his move to community-based custody. He was ordered to be transferred to the Bronx Residential Re-Entry Center, a halfway house in New York, and he was granted a furlough to travel unescorted on a commercial bus on July 17, 2012, from Pennsylvania to the Bronx. Gundy arrived at the Re-Entry Center as planned, and, on August 27, 2012, was released from federal custody there to a private residence in the Bronx. Gundy did not register as a sex offender in either Maryland or New York, as state law required, and was arrested and charged under 18 U.S.C. § 2250. Id. at 144. After the District Court granted Gundy’s motion to dismiss the prosecution for the absence of a trigger for SORNA’s registration requirement, this Court reversed the dismissal and reinstated the indictment, holding that the requirement was triggered because Gundy was “required to register” under SORNA no later than August 1, 2008. See id. at 145.

Upon the indictment’s reinstatement, Gundy renewed his motion to dismiss on the basis that the interstate travel requirement of the statute was not satisfied because he was still in custody when he traveled from Pennsylvania to the Bronx. The District Court denied the motion, holding that the statute did not include an exception to the interstate travel element based on a defendant’s custodial status. The District Court also held that, even if the statute did include a voluntariness or mens rea requirement, the allegations of the indictment were sufficient for that issue to be resolved at trial.

A bench trial followed on stipulated facts. The District Court found that each *641 element of the offense had been proven beyond a reasonable doubt, including the .interstate travel element and any volun-tariness or mens rea requirement that may apply, and thus found Gundy guilty of violating § 2250. Following a sentencing hearing, the District Court entered judgment imposing a sentence of time served and a five-year term of supervised release. Gundy now appeals from that judgment.

Section 2250(a) imposes criminal liability on anyone who (1) is required to register under SORNA; (2) travels in interstate or foreign commerce; and (3) knowingly fails to register or update a required registration. 18 U.S.C. § 2250(a). We held in our consideration of Gundy’s earlier appeal that Gundy satisfies the first requirement. There is no dispute that he knowingly failed to register, thus satisfying the third requirement. On appeal, Gundy asks us to read in an exception to the second requirement, travel in interstate commerce, for a defendant who crosses state lines while in federal custody. He contends that holding otherwise would violate the usual requirement of criminal law that criminal acts be committed voluntarily. The parties also dispute whether, on the stipulated facts and conclusions of the District Court following the bench trial, Gundy’s travel from Pennsylvania to New York was voluntary.

We decline to reach Gundy’s argument regarding the interpretation of § 2250(a). 1 Assuming arguendo that Gundy is correct and that the travel element contains an implicit voluntariness requirement, that requirement is easily met on the facts of this case. Although Gundy remained technically in federal custody when traveling to the halfway house in New York, the stipulated facts at trial are sufficient to support the District Court’s finding that Gundy’s travel was voluntary. On the basis of those facts, the District Court was free to conclude that Gundy made the trip in question willingly, as he authorized the initial transfer process and then traveled by bus to New York on his own recognizance. See United States v. Pierce, 224 F.3d 158, 164 (2d Cir. 2000) (noting that standard of review for sufficiency of the evidence is the same in a bench trial as a jury trial). We need not and do not reach the question of statutory interpretation because, even assuming Gundy is correct that interstate travel in § 2250(a) is limited to voluntary travel, the District Court reasonably found that the travel here was voluntary.

We have considered Gundy’s remaining arguments and find them to be without merit. 2 Accordingly, we AFFIRM the judgment of the District Court.
