Joseph Young appeals the district court’s decision affirming the denial of his application for disabled widower’s insurance benefits. Young has also filed motions to subpoena medical records and to appoint a private investigator.

Young has failed to address the district court’s determination that the Commissioner of Social Security’s decision was supported by substantial evidence. Accordingly, this claim is deemed abandoned. See Brinkmann v. Dallas County Deputy Sheriff Abner, 813 F.2d 744, 748 (5th Cir. 1987). Further, this court may not consider Young’s claim that city, county, and state officials knowingly withheld relevant medical records because this claim was not presented to the district court. See Leverette v. Louisville Ladder Co., 183 F.3d 339, 342 (5th Cir. 1999). Finally, Young’s allegations of conspiracy, discrimination, and torture are not relevant to the district court’s review of his disabled widower’s claim. Accordingly, the district court’s judgment is AFFIRMED. Young’s motions to subpoena medical records and to appoint a private investigator are DENIED.

AFFIRMED; MOTIONS DENIED.
