Although I won't argue with your description of Schiff, at that time he was a nothing. He had no real power as the GOP under Paul Ryan controlled the House and under McConnell, the Senate.
Surely you're not suggesting a Republican could have set Flynn up? (/s)
A repub like Ryan who was trying to organize an effort to get Trump to pull out of the race when teh Access Hollywood tape hit? A repub like Ryan who was Mitt’s running mate and held a constant threat of impeachment over Trump if he fired anybody else after Comey?
Naaaaa... you’re imagining things.
Schiff had enough power to get Nunes recused as chair of Intel and investigated. Under the worthless pussy Ryan democrats were given much more power than they should have had. Schiff was still on the Intel committee and could have had access to all kinds of info to leak.
