>BLACK, MANAFORT, & STONE
From what I remember, at the stage in Trump's campaign when the delegate stealing was going on and Corey was having a hard time fighting it, it was Stone (according to Stone) who told Trump to get Manafort on it. At that time the background info came out that Stone and Manfort go way back, all the way to Nixon. They were the whiz kids.
This doesn't indicate black or white hat for either, just wanted to point out that Stone is allegedly the middleman for getting Manafort into Trump's campaign.
