Suppose we elect a new President (feel free to call him “Tronald Dump” for the purposes of this exercise). Once assuming the presidency, he immediately begins to exercise every power available to his office. We’re talking pardoning mass murderers, trying to launch the nukes, ordering drone strikes on political opponents here on US soil, the works. Obviously he can’t just transfer money to his personal bank account, nor can he pass his own draconian laws as Congress has power in those areas.
My question is, what safeguards are in place to prevent the President from acting in these areas? For the sake of argument, let’s assume that he is of sound body and mind and therefore cannot be removed from his post for medical reasons. Impeachment/removal is another avenue that I would like to ignore for the sake of the hypothetical, although it would surely occur rapidly after some of the above incidents.
