What occurs if the President does not return a bill within 10 days?

If the President does not return a bill within 10 days, the bill automatically becomes a law, assuming Congress is in session. This provision is outlined in Article I, Section 7 of the U.S. Constitution, which describes the process for how a bill becomes law. The 10-day timeframe starts when the bill is presented to the President. If the President does not act on the bill during this window and Congress remains in session, the bill becomes law without the President's signature. This process ensures that legislation can still be enacted even if the President chooses not to intervene, thereby preserving the legislative momentum and allowing Congress to assert its legislative authority.
