I would if I was Mueller and given a deal the skate on charges against him being part of the coup once evidence was presented. That would be a treason charge presented to him at the White House. Put yourself in those Mueller shoes in that moment and ask yourself if you would take that deal and save your family in the process?
I did say there was the other possibility but it has less evidence being practiced.
He can bring Mueller in and quiz him on a "who do you think is qualified to run the FBI?" basis. Size him up.
I think it's more likely that Mueller was an unwitting honeypot for the active players.
