Steve Bannon, the former Donald Trump campaign CEO who spent six months working in the White House and returned to his old life at the helm of Breitbart News in August, is stepping down from his position as the conservative website's executive chairman.

The New York Times reported Tuesday on the departure of the outspoken ideologue whom Trump re-branded as 'Sloppy Steve' following the publication of a loosely reported tell-all book last week.

A source close to Bannon confirmed that his departure was the product of a revolt on the publication's board of directors, led by longtime financier and donor Rebekah Mercer.

Former White House chief strategist Steve Bannon is leaving his position as the conservative Breitbart News website's executive chairman, following a revolt by the board of directors.

Mercer, who has poured millions into Breitbart, tipped her hand last Thursday, saying in a statement: I support President Trump and the platform upon which he was elected. My family and I have not communicated with Steve Bannon in many months and have provided no financial support to his political agenda, nor do we support his recent actions and statements.'

Trump has given no quarter in his caustic regard for Bannon following the release of Michael Wolff's 'Fire and Fury.'

He tweeted last week that the political gossip tome is 'full of lies, misrepresentations and sources that don’t exist.'

'Look at this guy’s past and watch what happens to him and Sloppy Steve!'

Bannon brought Wolff into the White House and persuaded an unknown number of administration officials to cooperate with him.

And Bannon himself spoke harshly of Trump and his son Donald Jr. in the book, at one point calling the younger Trump 'treasonous' for holding a campaign-year meeting that included a Russian lawyer.

Bannon issued a quasi-apology on Sunday, telling the Axios news website that he supports Trump and his agenda.

'I regret that my delay in responding to the inaccurate reporting regarding Don Jr. has diverted attention from the president's historical accomplishments in the first year of his presidency,' he said.

Bannon never specifically denied telling Wolff the things attributed to him in the book, but said he regretted waiting five days to respond to 'inaccurate reporting.'

He also called Donald Trump Jr. an 'honorable man.'

But hours later a White House spokesman told reporters aboard Air Force One that it was too little, too late: 'I just don't think there's any way back at this point.'

Bannon had predicted in 'Fire and Fury' that the Russia probe, led by Special Counsel Robert Mueller, would focus on money laundering and ensnare the president's eldest son.

'They’re going to crack Don Junior like an egg on national TV,' he says in the book.

The president himself has piled on in recent days.

'I guess Sloppy Steve brought him into the White House quite a bit,' a prescient Trump said Sunday, 'and it was one of those things. That's why Sloppy Steve is now looking for a job.'

Breitbart CEO Larry Solov said in a statement that the company will find a way to transition Bannon out the door smoothly.

'Steve is a valued part of our legacy, and we will always be grateful for his contributions, and what he has helped us to accomplish,' Solov said.

A source with knowledge of Tuesday's events at Breitbart told DailyMail.com that Solov, a close friend and former roommate of the late Andrew Breitbart, argued most forcefully for the board to oust Bannon – saying he was 'damaged' and 'toxic.'

Breitbart News is named for Andrew Breitbart, the late conservative firebrand who died in 2012 of a heart attack at age 43

Bannon, though, said he was 'proud of what the Breitbart team has accomplished in so short a period of time in building out a world-class news platform.'

CNN reported that Solov addressed Breitbart employees on Tuesday via a Slack channel, saying that the outlet 'will continue doing what we do as well as anybody in the world, and that is report the news.'

An unnamed Breitbart employee told the network: 'Everyone seems stunned.'

Bannon, the ousted former Trump-whisperer, has been left a man without a country, and he also won't find sanctuary at the TV network most likely to house conservatives.

'Fox News will not be hiring Steve Bannon,' the network said in a statement late on Tuesday.

The Mercers, including Rebekah's father Robert, a billionaire financier, had already cut ties with Bannon and said they would no longer fund his political projects.

That backlash came after Bannon's failed attempt to shepherd the controversial former judge Roy Moore to the finish line of a U.S. Senate race Republicans expected to win in deep-red Alabama.

Moore defeated Trump's chosen candidate Luther Strange in a primary race but then was beset with accusations that he had fondled teen girls when he was in his 30s.

Following the release of early excerpts of Wolff's book last week, the White House left no doubt that it was cutting all ties with Bannon.

'Steve Bannon has nothing to do with me or my Presidency,' Trump said in an unusually lengthy statement full of pointed barbs.

'When he was fired, he not only lost his job, he lost his mind.'

'Steve pretends to be at war with the media, which he calls the opposition party, yet he spent his time at the White House leaking false information to the media to make himself seem far more important than he was. It is the only thing he does well.'

A former White House ally of Bannon told Axios: 'I've gone from being sympathetic to Steve to believing he's a genuinely bad guy, totally duplicitous. It's a shame. He has a lot of talent. But his self-destructive streak is unlike anything I've ever seen.'

In addition to his role with the Breitbart News website, Bannon also lost his seat on the company's radio program, which airss on the SiriusXM Patriot Channel.

'Breitbart News has decided to end its relationship with Stephen K. Bannon, therefore he will no longer host on SiriusXM since our programming agreement is with Breitbart News,' the satellite radio company said in a statement.
