Bernard Smith, Louisiana prisoner # 355507, was convicted in December 1999 after a jury trial of manslaughter and sentenced to 65 years in prison. The district court dismissed his 28 U.S.C. § 2254 petition as untimely. This court granted Smith a COA on the issue of “whether the district court erred in finding that Smith was not entitled to the benefit of the prison mailbox rule in connection with his direct review writ application to the state supreme court and thus, that his petition was [not timely] filed[.]” Smith v. Cain, No. 12-30680 (5th Cir. Oct. 26, 2012). Our review is limited to issues for which a COA has been granted. See 28 U.S.C. § 2253(c); United States v. Kimler, 150 F.3d 429, 430 (5th Cir. 1998); Lackey v. Johnson, 116 F.3d 149, 151-52 (5th Cir. 1997).

Although pro se briefs are afforded liberal construction, even pro se litigants must brief arguments in order to preserve them. See Yohey v. Collins, 985 F.2d 222, 224-25 (5th Cir. 1993); see also Fed. R.App. P. 28(a). Because Smith does not address the only issue upon which a COA was granted, he has abandoned that issue on appeal. See Yohey 985 F.2d at 224-25. The judgment of the district court is AFFIRMED.
