Jeffrey Johnson pleaded guilty to possession of child pornography and received a sentence of 120 months in prison. On appeal, he argues that the presumption of reasonableness given by this court to sentences within the advisory range of the Sentencing Guidelines returns the Guidelines to the unconstitutional mandatory status they held before United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). The presumption used by this court does not violate the Sixth Amendment. Rita v. United States, — U.S.-, 127 S.Ct. 2456, 2462-68, 168 L.Ed.2d 203 (2007). The judgment of the district court is AFFIRMED.
