Nolberto Soto-Soria (Soto) appeals his sentence from a guilty-plea conviction for re-entry of a deported alien. See 8 U.S.C. § 1326(b)(2). Soto argues that his sentence should be vacated and remanded because the district court sentenced him under a mandatory Guideline scheme held *532 unconstitutional in United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005).

As the Government concedes, Soto’s “Fanfan” claim is reviewed for harmless error. See United States v. Walters, 418 F.3d 461, 464 (5th Cir. 2005). The instant record fails to provide clear commentary from the district court regarding whether it would have imposed the same sentence under a post-Booker environment. See id. Accordingly, the district court’s “Fanfan” error was not harmless on the instant record. See id.

Soto also challenges the constitutionality of 8 U.S.C. § 1326(b). His constitutional challenge is foreclosed by Almendarez-Torres v. United States, 523 U.S. 224, 235, 118 S.Ct. 1219, 140 L.Ed.2d 350 (1998). Although Soto contends that AlmendarezTorres 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 Almendarez-Torres 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). Soto 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.

We VACATE Soto’s sentence and REMAND for resentencing.
