He may be the President of the United States of America but whether you support or oppose his politics, he is entitled to as much or little medical privacy as he desires.
Though in recent years we have seen assorted famous people telling us of their illnesses in order to encourage others to be more aware of their own health.
You'd better familiarize yourself with the 25th Amendment to the U.S. Constitution.
Section 1
In case of the removal of the President from office or of his death or resignation, the Vice President shall become President. Section 2
Whenever there is a vacancy in the office of the Vice President, the President shall nominate a Vice President who shall take office upon confirmation by a majority vote of both Houses of Congress.
Section 3
Whenever the President transmits to the President pro tempore of the Senate and the Speaker of the House of Representatives his written declaration that he is unable to discharge the powers and duties of his office, and until he transmits to them a written declaration to the contrary, such powers and duties shall be discharged by the Vice President as Acting President.
Section 4
Whenever the Vice President and a majority of either the principal officers of the executive departments or of such other body as Congress may by law provide, transmit to the President pro tempore of the Senate and the Speaker of the House of Representatives their written declaration that the President is unable to discharge the powers and duties of his office, the Vice President shall immediately assume the powers and duties of the office as Acting President.
Thereafter, when the President transmits to the President pro tempore of the Senate and the Speaker of the House of Representatives his written declaration that no inability exists, he shall resume the powers and duties of his office unless the Vice President and a majority of either the principal officers of the executive department or of such other body as Congress may by law provide, transmit within four days to the President pro tempore of the Senate and the Speaker of the House of Representatives their written declaration that the President is unable to discharge the powers and duties of his office. Thereupon Congress shall decide the issue, assembling within forty-eight hours for that purpose if not in session. If the Congress, within twenty-one days after receipt of the latter written declaration, or, if Congress is not in session, within twenty-one days after Congress is required to assemble, determines by two-thirds vote of both Houses that the President is unable to discharge the powers and duties of his office, the Vice President shall continue to discharge the same as Acting President; otherwise, the President shall resume the powers and duties of his office.
You'd better read it again, too:
Section 4
Whenever the Vice President and a majority of either the principal officers of the executive departments or of such other body as Congress may by law provide, transmit to the President pro tempore of the Senate and the Speaker of the House of Representatives their written declaration that the President is unable to discharge the powers and duties of his office, the Vice President shall immediately assume the powers and duties of the office as Acting President.
So while Donald Trump, the person, "is entitled to as much or little medical privacy as he desires," Donald Trump, the president, is not. Not if he wants to remain president in such circumstances.
The Vice President and the Cabinet can remove Trump from office. Trump could re-instate himself to power only to be removed again, leaving it up to Congress to decide the issue. If the concern is over health issues and his can't sufficiently convince Congress he is able to discharge the powers and duties of his office, Congress could then permamently remove him from office.
I didn't pretend to know US Law to that depth but I had assumed it does have the mechanism to continue the running of the country in the event of the president's incapacity.
I can see it would be right that senior ministers of state have reasonable knowledge of the president's health and ability to continue in post; and they and ultimately Congress the ability to remove hims from post if necessary; but the nature of the illness is not a general public need beyond a simple statement of serious illness.
If a seriously ill president personally wishes to say what is wrong with him, then that is his right and choice of course.
I shoud say I do not know how healthy or otherwise, Donald Trump may be.
I watched a video of one his speeches recently. He looked and sometimes spoke as if very tired, but may simply have been that: tired. He's no spring chicken and can be excused being weary!
He thinks the "Continental Army" was named after George Washington.
He thinks Washington seized victory from "Cornwallis of Yorktown" when actually Gen. Charles Cornwallis was of London and fought a losing battle at Yorktown.
He thinks the Continental Army "took over the airports."
