Explanation:

The veto power of the president according to the constitution of the United States is the power to refuse the approval or disapproval of a bill and therefore prevents it from becoming a law. President has 10 days excluding Sunday to sign a bill. But he can use veto to send it back to Congress explaining his objectives. The veto can be overridden by getting two-third majority of both the houses and senate but this case rarely possible because of the vote margin in the senate. Therefore it was used by the president to influence the decision-making process of the Congress.
