I’m not sure why, at this point with Comey admitting he was the leaker that prompted the assignment of the special console Mueller hasn’t been pressured to resign or recuse himself from any leak investigations.
When the Senators get Sessions and Rosenstein in front of them for questioning this week, they need to ask Rosenstein about the conflict of interest Mueller has and how to resolve it.
Rosenstein is in charge of supervising the Special Counsel within the limits of the Special Counsel regulation, and if the Special Counsel is no longer independent of conflicts of interest, then he needs to be replaced.
