Papadopoulos is now the Typhoid Mary of the Trump campaign

10. Yeah, many staffers are probably cooperating by now

Prosecutor Andrew Weissman got Enron chief financial officer Fastow to rat out higher ups by charging his wife, putting her at risk for ten years in jail. Weissman is willing to go to extremes of gratuitous cruelty to force cooperation. So there are probably several cooperating witnesses in the White House and elsewhere.

I doubt Trump can be convicted for Russia, hard to prove Trump conspired in their cyber theft crimes. It is legal to cooperate in defeating Hillary so long as no crime was involved. But Trump probably broke laws with fake loan applications, probably told people to hide or destroy evidence, which is obstruction of justice, probably a lot of business crimes of various sorts. And Mueller will find all of that.
