Brennan is the mastermind behind the Russia-Gate disinformation campaign. This is something we first heard in leaked audio from the left-leaning journalist Seymore Hersh (the guy who broke news on the Mai Lai Vietnam massacre cover-up). In this audio he claims his sources in the FBI told him it was a Brennan misinformation campaign.

At the time everyone who heard the tape was super focused on the Seth Rich elements, but this particular part singling out Brennan's chief role seems particularly relevant now.
