The company announced the move on Tuesday in a short post on its website. On Monday, the ousted White House staffer with alleged Nazi ties accidentally confirmed that White House staffers were told to speak to Michael Wolff, the author of Fire and Fury, the Trump tell-all book D.C. can't stop talking about. "And those statements still stand", he said.
Bannon had served as Breitbart's executive chairman since 2012. Wolff's book, released on Friday, sent shockwaves through the Trump administration with fiery quotes about the Trump family and numerous claims about the president's intelligence and competence.
"The three senior guys in the campaign thought it was a good idea to meet with a foreign government inside Trump Tower in the conference room on the 25th floor - with no lawyers".
But he goes on to say, in a hilariously misguided effort to discredit Wolff, that the author was indeed given access to the White House and staffers were asked to speak with him.

Diddy also posted an image to his Instagram account where the child's hoodie instead reads: "coolest king in the world". We are deeply sorry that the picture was taken, and we also regret the actual print.
There is, however, enough explosive force in Michael Wolff's "Fire and Fury" to demolish another pernicious threat to American democracy - the career of right-wing provocateur Steve Bannon.
In a statement, Trump said Bannon has nothing to do with his presidency and has "lost his mind". Bannon has tried to make amends. "He has been relentless in his advocacy for his father and the agenda that has helped turn our country around".
By contrast, Mr Bannon now seems to be striking a more conciliatory tone with the President, saying: "There was no collusion and the investigation is a witch hunt".
Bannon and Breitbart will work together on a smooth and orderly transition, the news site added.
