How does a bill become a law in Congress?

A bill becomes a law through several steps. First, a member of Congress introduces the bill in either the House or Senate. It is then referred to a relevant committee, which reviews, debates, and may amend it. If the committee approves it, the bill goes to the full chamber for debate and a vote. If one chamber passes the bill, it moves to the other chamber, where the process repeats. If both chambers pass different versions, a conference committee reconciles the differences. Once both chambers approve identical versions, the bill is sent to the President, who can sign it into law or veto it. Congress can override a veto with a two-thirds majority vote in both chambers.
