Question

What can the President do if Congress presents him with a bill that he doesn’t like? If the President chooses this option, is there anything Congress can do about it?

Answer 1

The President can veto the bill if he doesn't want it to pass as a law, but Congress does have the power to "override" that veto if they feel it is necessary. "Congress can override a veto by passing the act by a two-thirds vote in both the House and the Senate. (Usually an act is passed with a simple majority.)" - National Archives (.gov)
