Definition: The veto is the power of the executive (President or Governor) to prevent the enactment of a bill or resolution by refusing to sign the measure. The President has 10 days (excluding Sundays) to sign or reject a bill passed by Congress; failure to do sign is tacit approval of the bill, with one exception.
There are two forms of veto.
First, a regular veto occurs when the President returns the legislation to Congress, explaining the reason for the veto. Congress can overridde this veto by a two-thirds vote in both the Senate and the House, forcing a bill to become law over Presidential objection. If this occurs, the bill becomes law over the President's objections. Second, if Congress adjourns during the 10-day period, the bill does not become law.
