WikiLeaks, Snowden fleeing to Russia, Greenwald dialing up the pro-Kremlin talking-points over the years, the call-and-response "Russia, if you're listening," the hand-delivered letter from Trump to Putin by Rand Paul, the 4th of July closed-door Kremlin meeting by Republican congressman, the Trump tower meeting with Natalia Veselnitskaya, the Russian money laundered through the NRA, the strange Russian women amidst right-wing extremist groups. Manafort, Flynn, Stone regurgitating Kremlin talking-points while the Kremlin is telling RT to air as many Tucker Carlson clips as possible, Trump saying he trusts Putin's word against the unprecedented consensus of his own intelligence agencies and advisors, all the while trying to withdraw from NATO that otherwise has bipartisan support. I probably haven't even scratched the surface..
I think I counted a half dozen or so individuals arrested by the FBI in the past year or two trying to offload secrets to Russia.
If anyone hasn't listened to the Ultra podcast regarding the Nazi infiltration of America under the direction of Hitler to sow division under ideological and racial grounds in America, while successfully corrupting many Congressmen at the time... The parallels couldn't be more striking to today.
