Did Bush and Obama keep their predecessors' people in place? If I followed either one of them into office I'd replace their people asap. I'm surprised Trump took so long, especially when he figured out they were trying to oust him with lies.
It seems like it's not just predecessors' people, though. How many Trump administration positions are still filled with the people Trump originally put there? Offhand, half his cabinet (notably State, Defense, AG, and Homeland Security), his White House chief of staff and chief counsel, National Security Advisor, Director of National Intelligence, Director of the FBI, ... who am I missing?
