Appropriations Subcommittee Structure: History of Changes from 1920 to 2015 [October 13, 2015] [open pdf - 515KB]
"This report details the evolution of the House and Senate Appropriations Committees' subcommittee structure from the 1920s to the present. In 1920, the House adopted a change in its rules to consolidate jurisdiction over all appropriations in the Appropriations Committee. After the enactment of the Budget and Accounting Act of 1921, the House reorganized its Appropriations Committee by establishing for the first time a set of subcommittees to consider appropriations bills based on the administrative organization of the executive branch. The Senate followed suit in 1922, and the two chambers have continued under that basic organizational approach since that time. […] During the first session of the 110th Congress (2007), the House created the Select Intelligence Oversight Panel of the appropriations committee to oversee spending on federal intelligence activities. This panel was eliminated in 2011 at the beginning of the 112th Congress. This report will be updated to reflect any changes in Appropriations subcommittee structure."
