Appropriations bills provide the budgetary resources for the majority of Federal programs. The Appropriations Committee in each body has jurisdiction over annual appropriations. These committees are divided into subcommittees that hold hearings and review detailed budget justification materials prepared by the agencies within the subcommittee’s jurisdiction. Appropriations bills are initiated in the House. After a bill has been drafted by a subcommittee, the committee and the whole House, in turn, must approve the bill, usually with amendments to the original version. The House then forwards the bill to the Senate, where a similar review follows. If the Senate disagrees with the House on particular matters in the bill, which is often the case, the two bodies form a conference committee (consisting of Members of both bodies) to resolve the differences. The conference committee revises the bill and returns it to both bodies for approval. When the revised bill is agreed to, first in the House and then in the Senate, Congress sends it to the President for approval or veto.
