Gerald Thomas Williams appeals the 120-month sentence the district court 1 imposed after he pleaded guilty to possessing child pornography, in violation of 18 U.S.C. § 2252A(a)(5)(B). Williams argues that imposition of a statutory minimum sentence based on an alleged prior conviction violates his Fifth and Sixth Amendment rights as established in United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). Citing Blakely v. Washington, 542 U.S. 296, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004), he also questions the continued viability of Almendarez-Torres v. United States, 523 U.S. 224, 239-47, 118 S.Ct. 1219, 140 L.Ed.2d 350 (1998) (prior conviction is sentencing factor for court to decide).

We conclude the district court did not err in determining that Williams’s prior conviction qualified under 18 U.S.C. § 2252A(b)(2) as abusive sexual conduct involving a minor. See Booker, 543 U.S. at 244, 125 S.Ct. 738 (reaffirming prior-conviction exception to facts that must be admitted by defendant or proved to jury beyond reasonable doubt); United States v. Torres-Alvarado, 416 F.3d 808, 810 (8th *612 Cir. 2005) (“we are bound by AlmendarezTorres until the Supreme Court explicitly overrules it”); United States v. Johnson, 411 F.3d 928, 931 (8th Cir.) (Sixth Amendment does not require that fact of prior conviction be determined by jury; once court determines that prior conviction exists, characterization of that conviction is legal matter for court), cert. denied, — U.S.-, 126 S.Ct. 505, 163 L.Ed.2d 382 (2005).

Accordingly, we affirm.
