U.S. legislation refers to the laws and statutes created by the United States Congress, which consists of two chambers: the House of Representatives and the Senate. These laws are proposed as bills, which must be debated, amended, and voted on before they can be signed into law by the President. The legislative process involves several steps, including committee reviews and floor debates. Once a bill is approved by both chambers, it is sent to the President for approval or veto. If the President vetoes a bill, Congress can override the veto with a two-thirds majority vote in both chambers.
