Former CIA Director-turned-Twitter troll, John Brennan lashed out at Trump on Sunday evening after the President ordered the DOJ to investigate the FBI’s infiltration of his campaign.

Brennan also fired a warning shot to House Speaker Paul Ryan and Senate Majority Leader Mitch McConnell, claiming they will ‘bear the majority of the responsibility of the harm done to our democracy’ if they don’t stop Trump.

John Brennan warned Speaker Paul Ryan and Senate Majority Leader Mitch McConnell after Trump ordered the DOJ to review the FBI’s infiltration of his campaign.

Brennan tweeted: Senator McConnell & Speaker Ryan: If Mr. Trump continues along this disastrous path, you will bear major responsibility for the harm done to our democracy. You do a great disservice to our Nation & the Republican Party if you continue to enable Mr. Trump’s self-serving actions.

Brennan also sent out a peculiar cryptic threat to President Trump earlier on Sunday that had Twitter buzzing:

“Any man can make mistakes, but only an idiot persists in his error.” Marcus Tullius Cicero, (106-43 BC) — John O. Brennan (@JohnBrennan) May 20, 2018

On Monday morning former Secret Service agent Dan Bongino went on FOX and Friends and went after John Brennan.

Shortly after Bongino’s appearance President Trump tweeted out the transcript — and called Brennan’s bluff.

President Trump: John Brennan is panicking. He has disgraced himself, he has disgraced the Country, he has disgraced the entire Intelligence Community. He is the one man who is largely responsible for the destruction of American’s faith in the Intelligence Community and in some people at the top of the FBI. Brennan started this entire debacle about President Trump. We now know that Brennan had detailed knowledge of the (phony) Dossier…he knows about the Dossier, he denies knowledge of the Dossier, he briefs the Gang of 8 on the Hill about the Dossier, which they then used to start an investigation about Trump. It is that simple. This guy is the genesis of this whole Debacle. This was a Political hit job, this was not an Intelligence Investigation. Brennan has disgraced himself, he’s worried about staying out of Jail.” Dan Bongino
