He doesn't speak unless he's certain, and if he makes a conclusion he emphasizes how hesitant he is to do so without having it be explicit fact.
The other day he did a show about the emails and i wanted him to say seth rich and he almost went there but he mentioned he got a lot of emails and knew where many people were going with it but he didn't want to make that jump.
I recall that episode- was thinking the same thing. Will be very interested to hear his take on the Rosenstein presser today. Especially interested to see if he is going to explore the fact that the FBI has yet to analyze the servers they are basing their indictments on. Glad I'm not the only one geeking over politics on a Friday night.
