Tung Thanh Nguyen argues that the 12-month sentence of imprisonment imposed upon revocation of his term of supervised release violates Tapia v. United States, -U.S.-, 131 S.Ct. 2382, 180 L.Ed.2d 357 (2011) because the sentencing court selected the sentence based on the court’s belief that Nguyen needed drug rehabilitation. Nguyen was released from prison on October 12, 2012, therefore any argument that his prison term should be reduced is moot. United States v. Rosenbaum-Alan-is, 483 F.3d 381, 382 (5th Cir. 2007). DISMISSED.
