Sadly it Pence, hopefully he will not do anything big to make his Presidency anything to be remembered either way.
As for "Archie Bunker" Trump he is a pathological, compulsive liar, and not a very good one at that. So it will be his downfall.
IF J Edgar Hoover is still alive today, Trump would NOT be able to do anything to him. Try and fire him, nothing majorly good would come out for him. IF Hoover was around during the whole Watergate, we would have learn or seen, what he done with his power. To J Edgar Hoover it DOES NOT matter If you are Eisenhower, John F. Kennedy, LBJ, Richard Nixon, Ford, Jimmy Cater, Ronald Regan, H.W. Bush, Bill Clinton, W. Bush, Obama or Trump. He will do what he see fit and is NOT on anyone's side at all. It would be more then a field day for Trump with Hoover at the FBI.
