Article I, Section 7 of the Constitution establishes how bills become law. Every bill must pass the House and Senate in identical form, then go to the President. The President has 10 days (excluding Sundays) to sign or veto it. If Congress adjourns before those 10 days end and the President hasn''t signed, the bill dies—a "pocket veto" that can''t be overridden. If the President vetoes while Congress is in session, lawmakers can override with a two-thirds vote in both chambers. The clause explicitly exempts congressional adjournment votes and constitutional amendments, which skip the President entirely. In 1998, the Supreme Court struck down the line-item veto as violating this clause, ruling the President must accept or reject bills in full. The Presentment Clause gives the President a role in lawmaking while preserving Congress''s power to override executive objections through supermajority votes.
