Francisco Gutierrez-Mendez (Gutierrez) appeals the sentence imposed upon his guilty-plea conviction for illegal reentry. 8 U.S.C. § 1326. Gutierrez argues that the district court reversibly erred under United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), by sentencing him pursuant to a mandatory application of the Sentencing Guidelines.

There was no “Booker ” error or Sixth Amendment violation because the only enhancement to Gutierrez’s sentence was for his prior conviction. See Booker, 125 S.Ct. at 756, 769. Nevertheless, the district court committed “Fanfan” error by sentencing Gutierrez pursuant to a mandatory guidelines scheme. See United States v. Walters, 418 F.3d 461, 463-64 (5th Cir. 2005).

The Government concedes that Gutierrez preserved his Fanfan claim. As such, this court reviews the claim for harmless error. See Walters, 418 F.3d at 464. This court has rejected the argument that a Fanfan error is structural. See Walters, 418 F.3d at 463.

There is no indication in the record that the district court would have imposed the *865same sentence had the guidelines been advisory rather than mandatory. The Government has not satisfied its burden of showing that the district court’s Fanfan error was harmless beyond a reasonable doubt. See Walters, 418 F.3d at 463-64. Accordingly, we vacate the sentence and remand for resentencing in accordance with Booker.

Gutierrez argues that the “felony” and “aggravated felony” provisions of 8 U.S.C. § 1326(b)(1) and (b)(2) are unconstitutional on their face and as applied in his case in light of Apprendi v. New Jersey, 530 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000). Gutierrez’s 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 Gutierrez contends that Almendarez-Torres was incorrectly decided and that a majority of the Supreme Court would overrule Almendarez-Torres in light of Apprendi, 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). Gutierrez 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. Accordingly, Gutierrez’s conviction is affirmed.

This court need not address at this time Gutierrez’s remaining argument challenging the district court’s denial of his request for a downward departure. See United States v. Akpan, 407 F.3d 360, 377 n. 62 (5th Cir. 2005).
