The Senate ratified the selection of Senator Richard Shelby (R-AL) to chair the powerful Senate Appropriations Committee, following the resignation of former Senator Thad Cochran (R-MS) on April 1. Now the senior Republican member of the Senate Appropriations Committee, Senator Shelby replaced Senator Cochran as Chair of the Subcommittee on Defense and handed over his previous chairmanship of the Subcommittee on Commerce, Justice, Science, and Related Agencies to Senator Jerry Moran (R-KS).
