I don't have much to add to this, other than noting the pleasure of seeing the wheels of justice turning on such a lifelong slime bucket. And lifelong, too, very close associate of Trump. That's not remotely evidence of a crime, just noting that Stone carries with him a great-many decades of information about Trump that would likely be damning and worth trading for no legal costs and no prison time..
Stone has said that he'll NEVER testify against Trump, because he's insisted there's nothing to testify about. But then, that's what Michael Cohen said -- before flipping, and also being sentenced to prison. Being faced with long, actual jail time has its way of changing minds. Maybe not in this case. Though Roger Stone is not known for his high ethics, a man so enamored by the ethically-empty Richard Nixon that he has Nixon's face tattooed on his back, so I personally wouldn't rely on him being a Stand Up Guy. Or rely on him for anything.
(And let's be clear about something, too: Roger Stone has not said he won't flip and testify against Trump. He has only said he won't lie or "bear false witness" to help convict him. This is hardly the bold statement it appears on the surface. Indeed, I am 100% certain that Robert Mueller not only doesn't want Roger Stone -- but anyone -- to lie under oath.)
Trump has had a big meltdown today, of course. And sent out another tweet crying out (again) "No Collusion." The really big problem is that this is the first Mueller indictment that, in fact, actually and specially does point out collusion.
