Unpublished opinions are not binding precedent in this circuit.

Billy Ray Jackson appeals the magistrate judge’s order affirming the Commissioner’s denial of Jackson’s claim for disability insurance benefits. * On appeal, we confine our review to the issues raised in the Appellant’s brief. See 4th Cir. R. 34(b). Because Jackson’s informal briefs do not challenge the basis for the magistrate judge’s disposition, Jackson has forfeited appellate review of the magistrate, judge’s order. See Williams v. Giant Food Inc., 370 F.3d 423, 430 n.4 (4th Cir. 2004). Accordingly, we affirm. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before this court and argument would not aid the decisional process.
