Now we have to ask ourselves, why would Donald Trump’s campaign chairman be passing political polling data to a known Russian intelligence operative during the campaign? Well, the obvious answer is that Donald Trump knew exactly what he was doing when he hired Paul Manafort as his campaign chairman. He knew he was getting a guy who had the political skills to fix the anti-Russian plank in the Republican platform at the convention, and he knew that Manafort had extensive contacts with Ukrainian and Russian intelligence that went back more than a decade, and that Manafort could tap those contacts and pass information back and forth between the Trump campaign and the Russian government.
The other thing to notice when you look back at the service Manafort provided to the Trump campaign is the timing of his involvement. He went to work on the campaign during the time Russian GRU intelligence agents were hacking the servers of the Democratic Party and stealing their emails and political secrets. He met with Russian intelligence operatives in Trump Tower in advance of the Russians releasing those stolen emails, and he was running the campaign when the Russians began leaking the emails via WikiLeaks. He was there throughout the convention when Trump got the nomination for president on the Republican ticket, and he wasn’t ousted until Trump was well on his way as a candidate who was on the stump day after day talking about how much “I love WikiLeaks” and taking advantage of the Russian hacking.
The key figure who apparently tipped off Muller’s prosecutors that Manafort was lying to them during his agreement to cooperate was his former partner, Rick Gates. He was the deputy campaign chairman under Manafort and remained with the campaign after Manafort left. He was in constant contact with Manafort during the campaign and was present for the meeting with Kilimnik at the “Havana Room.”
