How can Congress override a presidential veto?

• A. With a majority vote in the House only.
• B. With a two-thirds vote in both houses.
• C. By a majority vote in the Senate only.
• D. By presidential endorsement.

Answer: (B)

When the President vetoes a bill, Congress can override that veto only if both the House and the Senate vote to pass the bill again by a two-thirds supermajority. If each chamber achieves that high level of support, the bill becomes law without the President’s signature. This two-thirds requirement in both chambers shows a need for broad consensus before overriding a veto. A simple majority in one chamber, or a majority in the other, isn’t enough, and a presidential endorsement doesn’t override a veto since it doesn’t change the necessary congressional vote.
