who has the power to approve or veto legislation
Article I, Section 7 of the Constitution gives the president the power to veto a bill passed by Congress. When the President vetoes a bill, it is returned to the Congress. If two thirds of both the House of Representatives and the Senate vote to override the veto, the bill becomes law without presidential approval. If they do not, then the bill dies. The Presidentâs power to veto legislation provides him with extraordinary power to influence legislation. The Congress will usually compromise with the President instead of presenting him with legislation they expect him to veto.
