“But he can’t go to trial unless he turns state’s evidence to Mueller?”
The Constitution guarantees him the right to a speedy trial. He can insist on that.
“And Trump can’t pardon him until he’s found guilty.”
Several have already referred to past precedent, including Pres. Ford pardoning Richard Nixon. So those who want Manafort and others to be beyond the reach of Trump’s pardoning power had better seek state charges against Manafort, et al. (The advantages of Federalism)
“And the whole shebang following Mueller’s report is dependent on Congress taking action?”
Any number of other persons can be charged and sent to prison, if juries convict.

You can’t expect to duplicate Argentina, where a massive left-wing protest forces the president to flee and resign. (smile).

BTW, the people here should pause to contemplate how much they desire US of America to become a ‘one party state’, and a one-thought dogma society, and whether we would be better off for it…
