Former CIA officer Daniel Hoffman said John Brennan is "doing Vladimir Putin's bidding" by speculating that the Russians have compromising information on President Trump.

During an MSNBC interview in March, Brennan, the CIA director under former President Obama, said Trump has a "fawning attitude toward" the Russian president and that may be because the Russians "have something on him."

'He's Disgraced the Country': Bongino Rips Brennan Over Trump-Bashing Tweet

After Trump called on the Justice Department to look into if the FBI infiltrated or surveilled his presidential campaign for political purposes, Brennan tweeted that Trump was on a "disastrous path" and doing a great disservice to the nation.

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. https://t.co/uAhgL6wfIC — John O. Brennan (@JohnBrennan) May 20, 2018

Trump fired back, quoting former Secret Service agent Dan Bongino on “Fox & Friends,” as Bongino accused Brennan of sparking the entire Russia probe and taking part in a politically motivated investigation.

...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 — Donald J. Trump (@realDonaldTrump) May 21, 2018

On "Hannity," Hoffman said Brennan comes across as a "partisan politician" with his unfounded speculation that Trump could be compromised by the Russians.

"John Brennan is doing Vladimir Putin's bidding," Hoffman said. "For someone who has criticized the Trump administration for the way they've handled Russia ... John Brennan is doing what Vladimir Putin wants by speculating about the president being subjected to blackmail, even though it's not true."

He noted that Brennan walked back his blackmail speculation several days later, but "the damage is done."
