Do you really think POTUS would show his hand and appoint Francisco to replace RR when he departs.
Nahh, I don't. Francisco may be the permanent replacement, but I believe POTUS will name one of his cabinet members as the replacement, which would only be good for 210 days.
So most likely, it will be someone older who is on his way out anyway.
Maybe Dan Coates will come in from DNI and do the job.
What the swamp going to say when one of the establishment comes in and disbands the Mueller team?
