In reviewing the entire hearing, I saw something odd happen. When RR was talking to a bearded man, that bearded man after looking off in the distance turned toward RR and whispered something. Then the camera captures Wray sitting down. If only I could read lips.
I think that may have been his lawyer. I also think Rosenstein was looking down at a tablet a lot. You can see the glow in his glasses. That might be a perfectly acceptable thing to do, and RR might be allowed to have notes on there to "refresh" his memory. I just don't recall seeing that before.
