What vote is required in both houses to override a presidential veto?

• A. Simple majority in both chambers
• B. Unanimous consent in both chambers
• C. Two-thirds vote in the House and Senate
• D. A three-fifths vote in both chambers

Answer: (C)

Overriding a presidential veto requires broad support in both chambers of Congress. The Constitution allows a vetoed bill to become law only if two-thirds of the members voting in each chamber approve it. In practice, that means a two-thirds vote in the House and a two-thirds vote in the Senate. If both chambers reach those thresholds, the bill becomes law despite the president’s objections. This ensures only measures with substantial, cross-chamber backing can override a veto. It isn’t about a simple majority, unanimous consent, or the three-fifths rule (which is used for ending debate in the Senate, not for veto overrides).
