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.
United States Congress Article One of the United States Constitution states, "All legislative Powers herein granted shall be vested in a Congress of the United States, which shall consist of a Senate and House of Representatives." The House and Senate are equal partners in the legislative processâ€”legislation cannot be enacted without the consent of both chambers. However, the Constitution grants each chamber some unique powers. The Senate ratifies treaties and approves presidential appointments while the House initiates revenue-raising bills. The House initiates impeachment cases, while the Senate decides impeachment cases.[1] A two-thirds vote of the Senate is required before an impeached person can be forcibly removed from office.[1]
