If a bill originates in the House of Representatives, it is proposed by a representative. Then, the proposed legislation is sent to a committee; once the committee releases the legislation, the entire House considers the bill for the purpose of amending, debating, or voting on it. If it passes by a majority of votes (218 out of the total 435 representatives), it goes to the Senate, where a committee considers it. The bill can then be released to the entire Senate for debate or a vote, and it can be passed by a majority (51 out of 100 senators). The Senate and House work together at that point. A conference committee made up of both representatives from the House and Senators works together to iron out any differences between the House and Senate bills, and, if the revised bill is again passed by the House and by the Senate, it is sent to the president, who has ten days to either veto it or sign it into law. Bills can also originate in the Senate (except for bills for raising revenue, which must originate in the House).
