What is required to override a presidential veto?

• A. A national referendum
• B. A two-thirds majority in both chambers
• C. A simple majority in both chambers
• D. A majority in the House only

Answer: (B)

Overriding a presidential veto requires broad, cross-chamber agreement. After the President vetoes a bill, Congress can try again, but it must pass the bill in each chamber with at least two-thirds of the members voting in favor. This two-thirds vote in both the Senate and the House is what allows the bill to become law despite the veto. The process isn’t a national referendum, and a simple majority—or a majority in just one chamber—doesn’t meet this higher threshold. The requirement ensures that only legislation with substantial support across both houses can override a veto.
