Who signs bills to become laws?

The President is responsible for signing bills into law following their passage by both the House of Representatives and the Senate. This step is a critical part of the legislative process in the United States. Once a bill has been debated, amended, and approved by both chambers of Congress, it is then sent to the President, who has the option to sign it, allowing it to become law. If the President does not sign the bill, it can still become law if Congress overrides a presidential veto with a two-thirds majority vote in both chambers.

The other choices refer to different roles within the legislative and executive branches. The Vice President's primary role is to preside over the Senate and cast a tie-breaking vote when necessary, while the Senate and the House of Representatives are responsible for debating, amending, and voting on legislation, but they do not have the authority to enact laws on their own without the President's approval. This process emphasizes the checks and balances that exist within the U.S. government, ensuring that no single entity has unchecked power in the law-making process.
