LOOK its simple
stone is one of the spies
he is deeply connected to manafort
manafort had been under investigation for years and despite a lot of evidence they never filed charges.
they didn't file charges because manafort has a lot of contacts and they probably offered manafort a deal to become an confidential /undercover informant. his task? be placed on the trump campaign to collect intel… manafort likely tapped stone to help him with this.
STONE IS A PIECE OF SHIT
remember when he claimed… "i'm such a big supporter of trump that they tried to poison me with pulonium"
fuck that guy
