Every law begins as a proposal made by a member of Congress, either a senator (member of the Senate) or representative (member of the House of Representatives). When the Senate or House begins to debate the proposal, it is called a “bill.” After debate in both houses of Congress, if a majority of both the Senate and House vote to pass the bill, it goes to the president. If the president wants the bill to become law, he signs it. If the president does not want the bill to become law, he vetoes it. The president cannot introduce a bill. If he has an idea for a bill, he must ask a member of Congress to introduce it.
