Do you remember that it just happened to occur right after the "grab 'em by the pussy" recording?
How do you think Wikileaks got that info? Who hacked the DNC?
And who released it, when asked to by Roger Stone?
Hint: The Russians
They did so work together. And Manafort provided the Russkies with internal GOP voter data so they could target their propaganda.
There were multiple lines of coordination.
