The responsibility for creating federal laws in the United States lies with Congress, which is the legislative body composed of two chambers: the House of Representatives and the Senate. Members of Congress propose, debate, and vote on legislation, which must then be signed by the President to become law. This checks-and-balances system ensures that multiple perspectives are considered in law-making, reflecting wider societal interests. Congressional powers also include oversight of the executive branch and the ability to amend or repeal existing laws.
