Mueller has (had?) a lot of connections to the DS players. But he's also a decorated Marine. Everything we seemed to know about him made him look like a traitor. The FBI wasn't a pillar of integrity under his watch. So I wonder if he faced a tribunal, and was given a choice? Or was he planted into the system to gather evidence and collect names? He looked pretty stressed out and befuddled when he presented his evidence to congress. And I think his DS connections go back many years.
