Kennon Bradford, federal prisoner # 26436-034, was convicted by jury verdict of being a felon in possession of a firearm. Bradford filed a motion to vacate, set aside, or correct his sentence, pursuant to 28 U.S.C. § 2255. The district court denied Bradford’s motion but granted a certificate of appealability (COA) on the issue whether his trial counsel rendered ineffective assistance by failing to file a motion to suppress the evidence obtained pursuant to the warrantless search of a rental car rented by Bradford’s girlfriend, Karen Barnes.

In order to prevail on a claim of ineffective assistance of counsel, Bradford must show that counsel’s performance was deficient and that the deficient performance prejudiced his defense. Strickland v. Washington, 466 U.S. 668, 687-94, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984). Failure to establish either prong is fatal to the claim. Id. at 697, 104 S.Ct. 2052.

The district court determined that counsel did not err in failing to challenge the search and the evidence it produced. Voluntary consent to a search is an exception to the general rule that warrantless searches are per se invalid. Schneckloth v. Bustamonte, 412 U.S. 218, 219, 93 S.Ct. 2041, 36 L.Ed.2d 854 (1973). Barnes rented the car in her name. Bradford acknowledges that Barnes consented to the search of the car. Her consent provided an exception to the warrant requirement. Id. Thus, counsel did not have cause for objecting to the search of the car and the subsequent seizure of the firearm. Counsel did not perform deficiently by failing to object or file a motion to suppress. It is unnecessary to evaluate the second prong of Strickland.

Although Bradford argues other issues in his appellate brief, he does not request an expansion of the COA grant. Therefore, our review is limited to the issue on which the district court granted a COA. United States v. Kinder, 150 F.3d 429, 430-31 & n. 1 (5th Cir. 1998); Lackey v. Johnson, 116 F.3d 149, 151-52 (5th Cir. 1997).

The district court’s judgment is AFFIRMED. Bradford’s motion for appointment of counsel is DENIED.
