I'm glad the spotlight is on Mueller, and I submit that he can "save face" by completing the investigation and turning a professional and thorough report to Rosenstein. Comey's with hunt investigations need to be handled and closed in a "convincing" manner, not summarily stopped.
Whoever gives Trump a clean bill is going to be pilloried by the press and the DEMs, and it looks to me that Mueller drew that straw.
Another benefit of all this is that by ratcheting up the accusation by innuendo, the RATs create a condition where quick resolution is valued. Unlike Comey, who could sit on the with hunt accusations forever, Mueller will be under pressure to deliver.
I concur with this.
Even the sturdiest and most upstanding members of the legal profession can't relish the idea of finding themselves a target of a Trump Twitter-storm.
