Both Flynn and Manafort were in bed with Putin. Manafort represented Putin's puppet in the Ukraine. Meanwhile, that puppet's opponent, a pro-US candidate, was nearly killed in an assassination attempt. His face is forever pocked-mocked as a result.
And Flynn was tight with KGB Putin via the state-funded/state-controlled 'news' outlet, Russia Today (RT). He was even invited to sit at Putin's private table, 2 seats away from him, at a special Russia Today event. He later got up and spoke at the event.
Your hatred for Russia and Putin has addled your brain. Sort of like someone who wears green colored lenses in their glasses, everything looks green.
I am not a Putin fan, I just like to see things as they are. And Flynn is a white hat, not a black hat.
