Trump was saying such nice things about Manafort just a week or two ago.

You guys are all talking about Manafort as if the U.S. government sending him to jail for life is the worst scenario. It's totally not. Russia has access to poison, and they're not afraid to use it. Manafort is a man who knows too much. If they decide that he's gone too far, then one day Manafort ends up beaten to death in prison, or maybe one of his daughters just disappears?

Honestly I suspect that if he is cooperating, then Russia has decided the jig is up, and to create as much chaos on the way down as possible.
