You’re right, they will. I’m thinking he strategically mentioned it. He also is calling on Sessions to end the investigation. Perhaps the offense has now taken the field!
A couple angles he's taken deviate slightly from the official record - why Comey was fired, on the record, has nothing to do with the Russia investigation but Rudy took the line that yeah, it was because Comey didn't do for Trump, what he did for Hillary, a public exoneration. Given the public debate right now, great angle for Rudy to take.
On Sessions and recusal, he (Rudy) didn't elaborate, but the recusal was well taken, and Rudy would have had exactly the same burden himself, for exactly the same reason. But whatever pressure goes to sessions during this is fine.
Rudy's real meaty criticism against Sessions was "recommendation of Rosenstein for DAG." Rudy did describe the conventional narrative about Trump meeting with Mueller, a couple days later Mueller is SC, and so on.
It's is going to be great watching this play out!
Good move rolling Rudy out into public.
