¶1 Stephen Paul Marcenko appeals the sentence imposed following his guilty-plea conviction for fraud in connection with identification documents in violation of 18 U.S.C. § 1028(a)(1). He argues that, in light of United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), the district court plainly erred in sentencing him under a mandatory guidelines system.
¶2 After Booker, it is clear that application of the federal sentencing guidelines in their mandatory form constitutes error that is plain. See United States v. Valenzuela-Quevedo, 407 F.3d 728, 732-33 (5th Cir.), cert. denied, — U.S.-, 126 S.Ct. 267, — L.Ed.2d-(2005). Marcenko’s contention that this error is structural and gives rise to a presumption of prejudice is unavailing. See United States v. Malveaux, 411 F.3d 558 (5th Cir.), cert. denied, — U.S. -, 126 S.Ct. 194, — L.Ed.2d-(2005). He must show that the error affected his substantial rights, and he has not done so. See Valenzuela- *375 Quevedo, 407 F.3d at 733-34. The judgment of the district court is therefore AFFIRMED.
