No, we KNOW he is the President. Read the Constitution. Read the laws.

The President has the right to fire for any or no reason any of the cabinet.

He obviously cannot fire the Speaker of the House. Why would you throw that in there? Sounds like the typical straw man argument that every illogical libTARD throws out.

The President has all power to fire Rosenstein and Mueller. He does not have the power to fire members of Congress.

According to “The Article II Constitutional Power”, the President has three
constitutional powers: enumerated, implied and inherent. The Enumerated
powers make the president the chief executive and Commander in Chief; give
the president power to veto legislation, grant pardons, and make treaties and
appoint ambassadors and other government officials including Supreme Court
justices; and provide that the president shall from time to time report to
Congress on the state of the union as well as to “take Care that the Laws be
faithfully executed, and shall Commission all the Officers of the United States.”
Implied powers are: Firing, Executive Privilege, Executive Agreements and
Executive Orders.
