Who signs bills into law?

The President is the individual who has the constitutional authority to sign bills into law in the United States. According to Article I, Section 7 of the U.S. Constitution, once both houses of Congress (the House of Representatives and the Senate) have passed a bill, it is presented to the President. The President can then either sign the bill, thereby enacting it into law, or veto it, which sends it back to Congress for possible reconsideration.

This process underlines the role of the President as the chief executive in the legislative process, highlighting the checks and balances integral to the American government structure. While other figures, such as the Vice President, Speaker of the House, or Senate Leader, play significant roles in guiding legislation and representing their chambers during debates and discussions, the actual signing into law rests solely with the President. This distinction is vital for understanding how legislation is enacted at the federal level.
