The Inspector General must be sued in her official role as opposed to her personal one. Refer to Relf v. Gasch, 511 F.2d 804, 808 n.18 (D.C. Cir. 1975); Stafford v. Briggs, 444 U.S. 527 (1980). The Inspector General or the Office of Inspector General cannot be sued by personal service on the Inspector General or any other employee because these provisions are required, Wallach v. Cannon, 357 F.2d 557 (8th Cir. 1966).
