What signs bills to the law?

In the United States, a bill is signed into law by the President after it has passed both the House of Representatives and the Senate. Once the bill reaches the President's desk, they can either sign it, allowing it to become law, or veto it, sending it back to Congress with objections. If the President takes no action for ten days while Congress is in session, the bill automatically becomes law. However, if Congress adjourns during that ten-day period and the President does not sign the bill, it is considered a "pocket veto" and does not become law.
