Juan Alfredo Enriquez appeals his conviction and sentence for illegal reentry. Enriquez challenges the constitutionality of 8 U.S.C. § 1326(b)(1) and (2) and, additionally, the district court’s application of the mandatory Sentencing Guidelines.

*603Enriquez’s constitutional challenge to § 1326(b) is foreclosed by Almendarez-Torres v. United States, 523 U.S. 224, 235, 118 S.Ct. 1219, 140 L.Ed.2d 350 (1998). Although Enriquez contends that Almendarez-Torres was incorrectly decided and that a majority of the Supreme Court would overrule Almendarez-Torres in light of Apprendi v. New Jersey, 530 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000), we have repeatedly rejected such arguments on the basis that AlmendarezTorres remains binding. See United States v. Garza-Lopez, 410 F.3d 268, 276 (5th Cir.), cert. denied, — U.S.-, 126 S.Ct. 298, 163 L.Ed.2d 260 (2005). Enriquez properly concedes that his argument is foreclosed in light of Almendarez-Torres and circuit precedent, but he raises it here to preserve it for further review.

Enriquez also contends that the district court erred in sentencing him pursuant to the mandatory Sentencing Guidelines regime held unconstitutional in United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 764-65, 160 L.Ed.2d 621 (2005). The sentencing transcript is devoid of evidence that the district court would have imposed the same sentence under an advisory regime, and, therefore, the Government has not borne its burden of establishing beyond a reasonable doubt that the district court’s error was harmless. See United States v. Walters, 418 F.3d 461, 464 (5th Cir. 2005). Thus, Enriquez’s sentence is vacated and the case is remanded for further proceedings. See id. at 466.
