Regarding Q, The Scaramucci model refers to the practice of temporarily appointing someone to a top cabinet or justice dept. position to carry out firings and removals of bad actors within. It originates from Trumps 10 day appointment of Anthony Scaramucci to interim white house communications director. Scaramucci got rid of some staff that needed to be gone but were being held onto by the previous director.  Apparently interim Attorney General Matthew Whitaker played the same role in the justice dept.
