The US Constitution dictates that majorities of both Houses of Congress must agree on all bills before they are forwarded to the president. however, the process of deciding whether to consider legislation in the first place is determined largely in the Committee System. While seniority is a factor, party leaders like the Speaker of the House and the Majority leader play a significant role in determining committee membership and who becomes a committee chair. the minority party has a leadership structure that includes a Minority leader and whips.
In the United States political system, the passing of a bill takes many stages and it is not a quick process.
First, a representative proposes a bill and is introduced in the hopper box and is assigned to a committee. The Bill is reported or approved and is sent to the House floor to debate. Then it is voted. If approved, it goes to the Senate. The Senate votes. If there is the need for further discussion, a committee is formed to discuss it, approve it and send it to the President who can veto or sign the bill.
