In the United States, the president has the authority to veto legislation passed by Congress as a check on the legislative branch's power. However, Congress can override a presidential veto through a specific constitutional process.12

To successfully override a veto, both the Senate and the House of Representatives must vote to approve the measure by a two-thirds majority in each chamber. If this threshold is met in both houses, the bill becomes law despite the president's objection.132

This process is a fundamental component of the system of checks and balances designed to ensure that no single branch of government holds absolute power. It is important to note that this override power does not apply to a pocket veto, which occurs when the president fails to sign a bill within 10 days while Congress is adjourned, rendering the veto absolute.24
