Dexter A. Brunson appeals following the district court’s 1 order affirming a 2012 administrative decision to deny a hearing on his third application for disability insurance benefits. Brunson has abandoned any challenge to the only ruling properly before this court by not raising it in his brief. See Freitas v. Wells Fargo Home Mortg., Inc., 703 F.3d 436, 438 n.3 (8th Cir. 2013) (issue is deemed abandoned where party fails to raise or discuss it in his brief); Carter v. Lutheran Med. Ctr., 87 F.3d 1025, 1026 (8th Cir. 1996) (per curiam) (dismissing pro se litigant’s appeal where brief presented no question for appellate court to decide because it identified no basis of alleged error by district court). Accordingly, the judgment of the district court is affirmed. See 8th Cir. R. 47B.
