    United States Court of Appeals, Fifth Circuit.
    Decided Aug. 17, 2005.
    James Lee Turner, Assistant U.S. Attorney, David Hill Peck, U.S. Attorney’s Office Southern District of Texas, Houston, TX, for Plaintiff-Appellee.

      Before BENAVIDES, CLEMENT, and PRADO, Circuit Judges.
   PER CURIAM:

Alberto Martinez-Mendez (“Martinez”) appeals following his guilty plea to a charge of being present illegally in the United States after deportation subsequent to conviction for an aggravated felony, in violation of 8 U.S.C. § 1326. Martinez argues that the “felony” and “aggravated felony” provisions of 8 U.S.C. § 1326(b)(1) and (2) are unconstitutional. He acknowledges that his argument is foreclosed by Almendarez-Torres v. United States, 523 U.S. 224, 235, 118 S.Ct. 1219, 140 L.Ed.2d 350 (1998), but he seeks to preserve his argument for further review in light of Apprendi v. New Jersey, 530 U.S. 466, 490, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000). Apprendi did not overrule Almendarez-Torres. See Apprendi, 530 U.S. at 489-90, 120 S.Ct. 2348; United States v. Mancia-Perez, 331 F.3d 464, 470 (5th Cir.), cert. denied, 540 U.S. 935, 124 S.Ct. 358, 157 L.Ed.2d 245 (2003). Martinez further asserts that, if Almendarez-Torres is overruled and if Blakely v. Washington, 542 U.S. 296, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004), applies to the Federal Sentencing Guidelines, his sentence could not be enhanced based on his prior convictions, unless they were submitted to a jury or admitted by him. As noted, Almendarez-Torres has not been overruled. This court must follow Almendarez-Torres “unless and until the Supreme Court itself determines to overrule it.” Mancia-Perez, 331 F.3d at 470 (internal quotation and citation omitted).

Martinez argues that the district court committed reversible error by imposing a sentence pursuant to the mandatory Federal Sentencing Guidelines system that was held unconstitutional in United States v. Booker, — U.S. -, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). We review for plain error. See United States v. Valenzuela-Quevedo, 407 F.3d 728, 732 (5th Cir.2005), petition for cert. filed (July 25, 2005) (No. 05-5556).

The district court committed error that is plain by sentencing Martinez under a mandatory Sentencing Guidelines scheme. See id.; United States v. Mares, 402 F.3d 511, 520-21 (5th Cir.2005), petition for cert. filed (Mar. 31, 2005) (No. 04-9517). However, Martinez has not carried his burden of showing that the district court’s error affected his substantial rights. See Valenzuela-Quevedo, 407 F.3d at 733-34; Mares, 402 F.3d at 521.

Accordingly, the district court’s judgment is AFFIRMED. 
      
       Pursuant to 5th Cir. R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5th Cir. R. 47.5.4.
