After a presidential veto, what vote total is required for a bill to pass both houses?

For a bill to successfully pass both houses of Congress after being subjected to a presidential veto, it requires a two-thirds vote in favor from both the House of Representatives and the Senate. This high threshold is in place to ensure that there is substantial legislative support for a bill even after the President has indicated disapproval.

The requirement for a two-thirds majority reflects the framers' intent to balance the powers of the legislative and executive branches, recognizing that a veto is a significant check on legislative action. A simple majority, while sufficient for initial passage, does not indicate the broad consensus needed to override a presidential veto. Unanimous consent is not a formal requirement; rather, it is often used in specific procedural contexts. Similarly, a three-quarters vote is not necessary at this stage. Thus, the two-thirds vote is the correct requisite to ensure the bill can still become law despite the opposition from the President.
