Sessions soiled himself with his recusal. If he were not removed, imagine how the Dems would howl if Mueller were giving their findings to Sessions to write the report.
He didn't mention Weissmann by name, but I'm pretty sure that's one of the two he was thinking of.
I hope Schiff gets served and I hope Flynn gets cleared. Mueller's team went hard after the facts and in the end there were no facts to support collusion or obstruction.
I.e., NO COLLUSION!!!
