Sorry, but when one looks at it logically, you are wrong and, actually, for what Comey/Rogers allow themselves, they are revealing some things and not others.
One, they have been counterintelligence "investigating" since July 2016, which one would have to assume, if they thought there was collusion, or as he put it coordination, with the Russians, how would they do that investigation from July on without surveiling, in one manner or another, the Trump team... which they admitted today they ARE investigating.
Second, Comey and Rogers can only answer for the FBI and NSA, not all the other agencies that could perform this legally and could speak for none that might do it illegally. We do know the Holder Justice department flagrantly assaulted US citzen rights in the notorious investigation of Fox news reporter James Rosen... so we know they are not overstepped beyond our civil liberty protections. Holder said he knew nothing of the investigations, but it was proven that he was the one that signed off on the Rosen case. So he was a proven liar and proven willing to go beyond the bounds against a US citizen.
How do you know who was the object of the surveillance? They admit to having a counterintelligence investigation going on since July of 2016. If they had an official investigation of the Trump team going on, why would this lead you to believe it was ONLY the wire tapping of the Russians?
Why would you wait on evidence when its right there before you. Why, because you don't believe the evidence, you don't believe the testimony of Comey and Rogers apparently.
