Who has the authority to sign bills into law in the United States?

The authority to sign bills into law in the United States rests with the President. According to Article I, Section 7 of the U.S. Constitution, once both the House of Representatives and the Senate have passed a bill, it is sent to the President. The President then has the option to sign it into law, allow it to become law without a signature, or veto it, returning it to Congress with objections. This process reflects the checks and balances inherent in the American political system, ensuring that the legislative branch and the executive branch have distinct roles in governance.

Other roles mentioned, such as the Vice President, Speaker of the House, and Senate Majority Leader, are significant but do not include the authority to sign bills into law. The Vice President primarily serves as President of the Senate and can cast tie-breaking votes but does not have signing authority. The Speaker of the House presides over the House and facilitates legislative proceedings, while the Senate Majority Leader guides the legislative agenda in the Senate. This separation of powers clarifies the specific responsibilities assigned to each position within the government structure.
