I pay little attention to the alphabet soup of names, up there - so my analysis is very armchair quarterback…
But there are several investigation and prosecution tracks moving in parallel. You have the investigation into FBI bias, the investigation into the Clinton Foundation, and the investigation which kicked up the NXIVM rabbit. We know all of those tie back to many of the same individuals who are also tied into Perkins-Coe(sp?) And my-mind-is-drawing-a-blank … The people who made the steele dossier, who Nellie was chatting away with in Russian over ham radio, like a moron.
All of those investigations would fall under the DOJ and Mueller's report would necessarily include most of them.
After which, Mueller will have to face charges for his own role in the Uranium One ordeal. The court will review the evidence (some of it newly declassified) to determine whether or not he broke the law or bears guilt of doing so.
