This seems to be bad news for Rosenstein. I expect Trump to now try to pressure Sessions to fire him. It also gives an excuse for GOP senate to willingly confirm a replacement. I wonder if they will try to put in somebody who will end the Russia investigation.
That said, I am very proud of my hero. He made a great decision in firing James Comey who deserved nothing less for giving us this hell of Trump rule. Hopefully he finds a way to keep his job. Rod Rosenstein tried his best to save America and he punished the one person who got us here (Comey).
