A bill becomes a law through a multi-step legislative process. It begins by being introduced in either the House of Representatives or the Senate by a member of Congress. If the bill passes through committee and floor votes in one chamber, it then moves to the other chamber to repeat the process. If the bill is approved by both chambers in identical form, it is sent to the President, who can sign it into law, veto it, or take no action and allow it to become law automatically.
