Alabama prisoner Sean Lee Best appeals the district court’s denial of his pro se federal habeas corpus petition, brought under 28 U.S.C. § 2254. This appeal is governed by the Antiterrorism and Effective Death Penalty Act of 1996 (AEDPA). A judge of this Court granted a certificate of appealability (COA) on:

Whether the district court erred by upholding the state court’s decision that the trial court did not err by failing to produce certain documents alleged to have contained material subject to disclosure pursuant to Brady v. Maryland, [373 U.S. 83, 83 S.Ct. 1194, 10 L.Ed.2d 215 (1963)], without independently reviewing the documents to determine if the state court’s resolution of the claim was a reasonable application of federal law.

No reversible error has been shown; we affirm. 1

On appeal, Best does not address the issue specified in our COA: whether the district court erred in upholding the state court’s rejection of his Brady claim without independently reviewing the documents to determine if the state court’s resolution of the claim was a reasonable application of federal law. Instead, Best argues solely the underlying merits of his Brady claim.

We are aware that Best is pro se: we are lenient when interpreting the arguments of pro se litigants. See GJR Invs., Inc. v. County of Escambia, 132 F.3d 1359, 1369 (11th Cir. 1998). But this leniency extends only so far. We will not act as de facto counsel for a pro se litigant. See id. Best has abandoned the issue on which we granted a COA. See Atkins v. Singletary, 965 F.2d 952, 955 n. 1 (11th Cir. 1992) (appellant abandons issue by failing to address it properly on appeal).

AFFIRMED.
