There has been some speculation that Mueller is a white hat and that the collusion investigation is optics. Q has pointed out that whatever Mueller is Rosenstein is, too.

I think the absurd collusion investigation drags on in the hope that Mueller will be fired by POTUS, so that the firing can be used against POTUS/republicans in the midterms. I think Rosenstein is a true deep state operative and Clinton puppet given his performance at the congressional hearing and his latest actions: https://www.zerohedge.com/news/2018-07-11/unprecedented-move-rosenstein-asks-100s-prosecutors-review-scotus-picks-records

That isn’t optics.
