MEMORANDUM **
Henry Clay Howard, III, appeals pro se from the district court’s denial of his 28 U.S.C. § 2255 motion alleging insufficient evidence to support his conviction and sentence and ineffective assistance of counsel. We have jurisdiction pursuant to 28 U.S.C. § 2253, and we affirm.
Because Howard stated in a valid plea agreement that he was guilty of knowing possession of cocaine base with intent to distribute, and possession of a weapon during or in relation to a drug trafficking crime, his claim that the evidence was insufficient to sustain the conviction and sentence on these counts is barred. See United States v. Mathews, 833 F.2d 161, 164 (9th Cir.1987) (a guilty plea conclusively proves all factual allegations contained in the indictment).
Similarly, Howard’s assertion that his counsel was ineffective for failing to challenge his conviction and sentence on the grounds that the evidence was insufficient fails because he admitted guilt on those counts in the plea agreement and at the change of plea hearing, and does not argue now that he would have gone to trial but for his counsel’s errors. See Strickland v. Washington, 466 U.S. 668, 686, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984).
To the extent that Howard raises issues not included in the certificate of appealability (“COA”), we construe it as a motion to broaden the COA and we deny the motion. See 28 U.S.C. § 2253(c)(2); 9th Cir. R. 22-l(e).
AFFIRMED.
