Meh, it's a stretch to say that Ryan confirmed evidence, but merely that nobody in congress was presented with evidence that disproved them?
Weird, lawyer-like wording, but Ryan didn't come out and say they exist.
For me, the key point is Ryan's one word response....
BAIER: So you believe it to be true? (this was in reference to the previous statement: And then in October they renew it and
they do start a wiretap with some computer and Russian banks and it doesn’t show up anything, by reporting. Have you heard that? )
RYAN:
Yes.
So, a surveillance was actually done.
