Article II Section 1. The executive Power shall be vested in a President of the United States of America
It doesn't say "some of the executive power", nor does Article I mention anything about being able to create new executive powers vested in other entities. So if the president is the only one who has been vested with the executive power, how can a functionary of the executive promulgate a regulation that disagrees with the president? Ultimately the House can impeach and the Senate convict, possibly disqualifying them from federal office.
