Quick Summary

In government, a veto is an executive's power to reject a bill or proposal. This action prevents legislation from becoming law. There are different types of vetoes, including the regular veto, which can be overridden by Congress, and the pocket veto, which occurs when the executive fails to act on a bill within a specific timeframe after the legislature adjourns, making the veto absolute. Some executives also have an item veto or line-item veto, allowing them to reject specific parts of a bill without rejecting the entire measure. The power of veto serves as a check on legislative actions.1234
