What are veto overrides?

Veto overrides occur when Congress passes a bill again despite it having been vetoed by the President. This process is a crucial aspect of the checks and balances system established in the U.S. Constitution, designating that Congress can affirm its legislative decisions even if the President does not agree with them.

When the President vetoes a bill, Congress has the authority to challenge that veto. To successfully override a veto, a two-thirds majority vote in both the House of Representatives and the Senate is necessary. This action demonstrates Congress's power and ability to enact legislation even in the face of a Presidential objection, reflecting the dynamic interaction between the legislative and executive branches of government.

The other options do not accurately represent the concept of veto overrides. Ignoring the President's opinion does not involve any action on specific legislation, and an automatic passage of a bill after 10 days pertains to a different situation that involves the President's inaction. Lastly, a President unilaterally canceling a bill does not occur in the legislative process, as the veto power specifically requires a formal rejection of the bill followed by the possibility of an override.
