which house of congress has the power to introduce appropriation bills
Appropriation bill According to the Origination Clause of the United States Constitution, all bills for raising revenue, generally tax bills, must originate in the House of Representatives, similar to the Westminster system requirement that all money bills originate in the lower house. Traditionally, though, appropriation bills also originate in the House of Representatives.[8][9] House appropriations bills begin with "H.R.", meaning "House of Representatives". In reference to revenue bills, the Constitution also states that the "Senate may propose or concur with Amendments as on other Bills." As with revenue bills, the Senate and House each drafts and considers its own appropriation bill. The Senate then "cuts-and-pastes," substituting the language of its version of a particular appropriation bill for the language of the House bill, then agrees to the bill as amended.
Procedures of the United States House of Representatives It is in Committee(s) that bills get the most scrutiny and attention and that most of the work on a bill is done. Committees play an important role in the legislative process by providing members the opportunity to study, debate and amend the bill and the public with the opportunity to make comments on the bill. There are three types of House Committees, these are: 1) standing committees elected by members of the House, 2) select committees appointed by the Speaker of the House, and 3) joint committees whose members are chosen according to the statute or resolution that created that committee. As the House Rules limit the amount of floor debate on any given bill the committees play an important function in determining the final content and format of the bill.
