Trump's SC will be someone from the list he released before the election.
My prediction for Gowdy is that he'll be replacing RR. Based on how viably pissed off he was at the RR hearing, I can think of no better person to fill the role. At his swearing in he should be presented with a ceremonial gold-plated meat tenderizer as a symbols of the proper beat-down he will be giving the Deep State.
