If you take last weeks 4chan "insider" info drop....the answer is yes, duress for Mueller and eventual quitting the FBI over it. Bannon shops Mueller to Trump and is pardoned and placed as Special Counsel because he knows where the bodies are. Comey and Rodenstein are supposedly dirty.....which Rodenstein does not make sense in this story and still be head of Mueller.
Still waiting on that one but Mueller is supposedly going after all the dirt on both parties in this scenario.
Trump could be pulling the Deep State’s own tricks back on them. For instance, putting Petraeus in CIA, knowing they had the goods on him to keep him in line. Rosenstein and Mueller are both absolutely filthy with the Uranium One thing, and Trump could be letting them know that if they don’t serve the truth now it will be all up for them.
