 The Congress first overrode a presidential veto (passed a bill into law notwithstanding the President's objections) on March 3, 1845.All U.S. states also have a provision by which legislative decisions can be vetoed by the governor.In addition to the ability to veto an entire bill as a "package", many states allow the governor to exercise specialty veto authority to strike or revise portions of a bill without striking the whole bill.
