MEMORANDUM **
Fred Robison appeals from the 120-month sentence imposed following a guilty-plea conviction for conspiracy to possess with intent to distribute and to distribute a controlled substance, in violation of 21 U.S.C. § 846. We have jurisdiction pursuant to 28 U.S.C. § 1291, and we affirm.
Robison contends that trial counsel was ineffective for failing to further investigate whether he was eligible for safety-valve relief. The record in this case is sufficiently developed for us to determine that Robison did not receive ineffective assistance of counsel. See United States v. Labrada-Bustamante, 428 F.3d 1252, 1260-61 (9th Cir.2005). Specifically, the record reflects that counsel investigated the validity of the prior conviction that made him ineligible for safety valve consideration, and undertook a great deal of effort to attack the conviction in state court. Because Robison fails to demonstrate that counsel’s performance was deficient, his claim fails. See Strickland v. Washington, 466 U.S. 668, 687-90, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984).
AFFIRMED.
