But the end of Bannon's tenure at Breitbart came amid tension between the White House and the former strategist who had fashioned himself as the general leading the rebellion against the GOP establishment on Trump's behalf.
Bannon drew heavy fire from the president and from his allies for his highly critical comments in a new book about the Trump White House.
Trump quickly disowned Bannon, saying, "Steve Bannon has nothing to do with me or my Presidency". It's unclear what Bannon, who joined Breitbart in 2012, plans to do next, or who might take his place at Breitbart.
Bannon 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". Mr Trump has a record of threatening lawsuits without ever filing them, but even the threat can be costly to the putative target.
"She is a force of nature".
"Fire and Fury" is not entirely inconsistent with Wolff's prior statements.
CIA Director Mike Pompeo said Trump was "completely fit" to lead the country.
Bannon's departure from Breitbart was announced on Tuesday internally to staffers, who were reportedly stunned. It's not as if Bannon's broke and despondent, hopeless and headed for total irrelevancy. But as he tried to regroup to far right, he was facing Trump.
"Theirs was a consciously quixotic mission". Breitbart's Jewish employees said he made sure they were able to observe Shabbat and Jewish holidays.
Opening The Late Late Show, host James Corden was also quick to mention Bannon, only to hysterically laugh after an audience member began laughing merely when he brought up the former White House aide's name.
In Mr Trump's view, Mr Bannon's great sin with regard to Wolff's book was to say highly negative things about the President's family.
"This is the reaction of people not in charge", he said. According to Macmillan CEO John Sargent, digital sales already top 250,000 copies, an extraordinary number for a nonfiction release and likely boosted by the scarcity of the hardcover edition.
"Bob believes that human beings have no inherent value other than how much money they make", an unnamed co-worker told the New Yorker. But as Trump's own press secretary has acknowledged, the author had more than a dozen interactions with administration officials at 1600 Pennsylvania Avenue.
In August last year he was fired following a Unite the Right rally in Charlottesville which became violent.
"I think you have nailed the most important point: who at this hour is Steve Bannon's constituency?"
Trump responded with a written statement disavowing his one-time White House adviser. "And in that beat, which often merits a front-page story, the beat is that President Trump is an aberrant president".
