That's a stunning sentence. It suggests that Trump's circle knows he committed crimes and knows that Paul Manafort knows about those crimes.
And Manafort is likely to flip.
Somehow people in Trump's circle knew or strongly suspected what was going down with him and Russia.
(And maybe it's time to make note of who's always been a skeptic on Trump crimes—whatever the evidence—and who's seen from Day 1 there was no reason for skepticism.)
