I think he sees the handwriting on the wall finally.
His repeated attempts at trying to convince the public "that-there-was-Trump-collusion-with-Russia-but-we-just-haven't-found-it-yet" have gone flat.
Now it looks like the only collusion was the conspiracy among the democRATS to get Hillary across the finish line and, when that didn't happen, to destroy Trump with a phony "Russia collusion" investigation via a special prosecutor.
Turnaround is fair play and now the hunters are the hunted.
Come on, Schiff. Say something. Hello? Cat got your tongue?
