According to one of the fundamental rules of the Constitution, the ultimate authority in the United States is held by "The people" - the President, Senate and the Supreme Court are only there to enforce and represent this authority.
The President in the executive branch can veto a law, but the legislative branch can override that veto with enough votes. The legislative branch has the power to approve Presidential nominations, control the budget, and can impeach the President and remove him or her from office.
