ORDER
Briawn Jackson raises two issues on appeal: (1) that an enhancement of his offense level based on a finding of loss amount that was neither proven to a jury beyond a reasonable doubt nor stipulated to by Jackson violates the ex post facto *419and due process clauses of the Constitution, and (2) that an increase of his mandatory minimum sentence based on a finding that he brandished a weapon that was neither proven to a jury beyond a reasonable doubt nor stipulated to by Jackson violates his Sixth Amendment right to a jury trial and the ex post facto and due process clauses of the Constitution. Jackson concedes that both issues are foreclosed by precedent — the first by United States v. Jamison, 416 F.3d 538 (7th Cir.2005), and the second by Harris v. United States, 536 U.S. 545, 122 S.Ct. 2406, 153 L.Ed.2d 524 (2002); see also United States v. Jones, 418 F.3d 726, 731-32 (7th Cir.2005) — and brings his appeal solely to preserve the issues for presentation to the Supreme Court. We agree that Jackson’s arguments are foreclosed by precedent.
AFFIRMED.
