IT’S IN THE U.S.CONSTITUTION - the only branch of government with the power to remove a sitting President is Congress. The legislative branch, including SCOTUS, does not have the power.
Do you understand the situation now?
Congress has, in the past, removed sitting Senators for being ineligible, and their names stricken from the Congressional records. So it can be done.
BTW, have I offended you, somehow? The tone of your post to me suggests that I have.
