Who has the power to veto bills?

The power to veto bills is vested in the President of the United States. This authority is outlined in the U.S. Constitution, specifically in Article I, Section 7. When Congress passes a bill, it is sent to the President, who can either approve it or reject it by exercising a veto. A veto sends the bill back to Congress with the President's objections. Congress can override this veto with a two-thirds majority vote in both the House of Representatives and the Senate, allowing the bill to become law despite the President's rejection.

This process ensures a system of checks and balances within the government, allowing for a degree of presidential influence over legislation. The other entities listed—the Vice President, the Senate, and the House of Representatives—do not possess the direct authority to veto legislation. The Vice President's role is primarily to cast a tie-breaking vote in the Senate, while the Senate and House of Representatives can propose and pass bills but lack the ability to unilaterally reject them without the President's involvement.
