posted by O-TrapI can believe he'd off himself, given the position he's in. I mean, his choices are effectively (a) go to prison for the rest of his natural life, or (b) try to cut a deal by pissing off a bunch of rich and powerful people who have already shown they have no problem victimizing people and breaking the law.
Well, there's unknown option C) that he already mostly beat federal charges. I wouldn't bet he gets convicted. I could see the charges mysteriously being dropped, or dismissed by a judge. If all you have is one new witness (no idea), that's probably not enough for a jury even if she's a good witness.
I'm not sure ratting on powerful people will help him - because you're assuming NY or the feds want to charge those people (Trump, sure, but not anyone else). But if he has the goods, those powerful people are already putting the fix in on his behalf (like, I assume, they did before).
