At this point, it wouldn't be surprised if the IC is primed to try and upend the prez and certain members of Congress if they have certain connections to Russia.
At this point I think we can say Nunez is the most likely at the top of the shit list, I would love if Chaffetz could be taken down too but he is just partisan and scummy asshole more then likely. Nunez at minimum was on the trump transition team and has already been exposed as someone attempting to stifle the investigation in the public eye after being asked to by Trump surrogates.
