See Local Rule 36(c). PER CURIAM: Michael Vertoin Saunders appeals the district court’s order denying his motion to reduce his sentence due to his health prob- lems, which the district court construed as a motion filed under Fed. R. Crim. P. 35. We have reviewed the record, the district court’s opinion, and Saunders’ informal appellate brief. Because he failed to challenge on appeal the basis for the district court’s ruling, Saunders has not preserved any issue for our review. 4th Cir. R. 34(b). Accordingly, we affirm on the reasoning of the dis- trict court. United States v. Saunders, No. CR-96-204-DKC (D. Md. filed Dec. 15, 2000; entered Dec. 18, 2000). We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process. AFFIRMED 2
