Tomas Gardea-Calleros, federal inmate # 11508-180, appeals from the denial of his motion for reconsideration of his sentence which the district court construed as a motion for reduction of sentence. He argues that the Government improperly relied on his prior deportation as an element of his offense under 8 U.S.C. § 1326 because that prior deportation was the result of a due process violation. Because the district court was without authority to modify the imposed term, the denial of the motion for a sentence reduction is AFFIRMED. See United States v. Bridges, 116 F.3d 1110, 1112 (5th Cir. 1997).
