Sorry to burst anyone's bubble on this, if only partially anyway, but Schiff, Shumer, Nadler ET. AL will not be included in any criminal prosecutorial process'. Investigations will be done, and they can be censured, possibly even forced into retirement, but criminal charges are not in the cards there. They have Congressional Immunity, any crime they commit within the walls of the Capitol Building falls under this immunity clause, they knew that going in.

On the other hand, we all may just get some satisfaction in that arena with Brennan, Clapper and Comey, possibly even Yates and a few others i.e. Killary, McCabe, Strzok and Page.

I doubt POTUS will let Barr go after Obama, it's not prudent to prosecute a previously sitting president, looks bad, but if Barry keeps running his mouth he might just get kicked in it if he's not careful.
