What is one of the President’s checking powers in the United States government?

The President's power to veto Congressional legislation is a crucial checking power within the framework of the United States government. This power allows the President to reject bills passed by Congress, which serves as a check on legislative authority. By doing so, the President can prevent legislation that they believe is unwise or harmful from becoming law. This veto power is a fundamental aspect of the system of checks and balances designed by the framers of the Constitution, ensuring that no single branch of government gains excessive power.

In the context of the other choices, executive privilege pertains to the President's ability to withhold information from other branches of government, but it is not a direct mechanism of checks and balances over legislative actions. The approval of judges nominated by the Senate is a power that belongs to the Senate, not the President, and while the President nominates judges, he does not have the power to approve them. Lastly, there is no mechanism for the President to approve judges nominated by the House of Representatives; the House does not have a role in the judicial appointment process.
