Gowdy asking for evidence for collusion from a CIA Director is most stupidest thing to hear from someone who is supposedly a former federal prosecutor. He should know that you don’t ask a CIA director about evidence. Evidence is something that investigative agencies like FBI built based on the available information and according to the legal codes. All CIA could do is to refer to FBI if they observe a disturbing pattern in the intercepts. So Gowdy should be asking FBI about the evidence of collusion, not a former CIA director. Seems like Gowdy is trying to make current Republican President look good in midst of the current scandal.
