Andrew Spotted Elk directly appeals the senténce that the district court 1 imposed upon revoking his supervised release, arguing that his six-month prison sentence is substantively unreasonable. Upon careful review, see United States v. Miller, 557 F.3d 910, 915-16 (8th Cir. 2009) (appellate review of revocation sentence), we conclude that the within-Guidelines-range sentence is not substantively unreasonable, see United States v. Petreikis, 551 F.3d 822, 824 (8th Cir. 2009). We grant counsel’s motion to withdraw. The judgment is affirmed.
