Explanation:

Bills are proposals for a new law or a change to an existing one; in the U.S., they can only be introduced by members of Congress at any time the chambers are in session. If a bill is first proposed in the House of Representatives, for example, and is passed by a majority vote, then it bill goes to the Senate so that their members can vote on the bill too. If it is also passed by a majority vote in the Senate, then it goes to the President for signature and it becomes a law. This process, however, may take days, weeks or even months.
