That didn't take long.
Steve Bannon returned to Breitbart News as executive chairman on Friday following his ouster from the White House, the far-right website announced in a press release.
Bannon chaired the outlet's evening editorial meeting, the press release added.
"The populist-nationalist movement got a lot stronger today," said Breitbart News Editor-in-Chief Alex Marlow in a statement. "Breitbart gained an executive chairman with his finger on the pulse of the Trump agenda."
What Bannon is thinking
The question now is whether Bannon will be an ally or a thorn in the side of the Trump administration outside the White House, where he has apparently already returned to his role as head of Breitbart, the right-wing news site he ran until he joined Trump's campaign a year ago.
However that unfolds, Bannon is expected to remain tightly connected to the billionaire conservative father-daughter pair Robert and Rebekah Mercer, who are major investors in Breitbart News and top Trump donors.
Bannon returned to the role of executive chairman of Breitbart News and chaired the evening editorial meeting, the publication's White House correspondent reported Friday evening.
Both Bannon and Trump spoke with the Mercers in recent days, a White House official said.
A White House ally who has talked to Bannon said the outgoing chief strategist does not want to go to war with Trump. Bannon is making that clear to close associates in response to Breitbart editor Joel Pollak tweeting #WAR.
"That's not where Steve's head is at," this source said. "He's been fighting for the exact same things that the President has been fighting for."
This source quoted Bannon as saying "I want (Trump) to succeed."
Still, as his firing appeared increasingly likely, Bannon downplayed concerns about being booted from the White House and argued that he would be a more powerful force from the outside, sources close to Bannon said.
He has privately told associates he would return to his "killing machine" -- Breitbart -- if he was forced to leave for the White House and has said he would be able to more easily target some of his White House rivals -- like chief economic adviser Gary Cohn and national security adviser H.R. McMaster -- from the outside, the sources said.
Bannon has also worked in recent weeks to put the pieces in place for his agenda to live on without him at the White House, working on hardline trade initiatives in his final weeks.
After pushing the President to start the process of investigating Chinese trade abuses, Bannon also laid the groundwork for a series of aggressive trade actions designed to impose a harder line against China, the sources said.
In his final days at the White House, Bannon was continuing to work up schedules for the rollout of trade initiatives that would come in September, long after he expected to be forced from the White House, the sources said.
"We're going to run the tables on these guys," Bannon told The American Prospect in an interview earlier this week.
A quick and contentious tenure
Bannon's turbulent White House tenure was marked by controversy.
In the administration, Bannon frequently butted heads with other advisers to the President, feuding with son-in-law and senior adviser Jared Kushner, chief economic adviser Cohn and other more moderate members of the President's administration whom Bannon branded as "globalists."
Bannon was often suspected by colleagues of badmouthing them to reporters and he rubbed colleagues the wrong way by attempting to ramrod his ideological positions.
"Steve was never a team player," a senior administration official said.
Bannon viewed himself as the populist defender of Trump's campaign promises in the White House, working daily to tick off items from the list of promises that hung on the walls of his West Wing office.
Bannon focused especially on pushing a hardline trade agenda, recently working to cue up a series of trade policies to aggressively target Chinese foreign trade abuses and work toward rebalancing the trading relationship between the US and China.
Bannon was an influential voice inside the White House, feeding and encouraging Trump's nationalist and populist instincts.
In the process, he garnered an infamous reputation as a puppet master pulling the strings in the Oval Office, with pop culture portrayals ranging from the moniker "President Bannon" to his depiction as the grim reaper on "Saturday Night Live." Those portrayals -- coupled with a Time Magazine cover that declared him "the great manipulator" -- often angered Trump, who chafes at being outshined.
But the reality is that while Bannon was an influential figure at Trump's side, he was hardly the all-powerful aide so many sought to portray him as.
He did not always come out victorious in his feuds with fellow White House aides and Trump did not always heed his counsel.
Still, Bannon served as a daily reminder to Trump of his populist campaign promises and his bellicose political instincts. Bannon's rivals in the White House argued that he encouraged the President's worst instincts, while his allies said he was keeping the soul of Trump's movement alive.
The fiery chief strategist also led the charge against proposals by national security officials to deepen US military involvement in Afghanistan, feuding vocally during meetings of the National Security Council with McMaster and working behind the scenes to water down hawkish proposals for troop increases and a longer-term US military commitment.
The President is meeting Friday with members of his national security team at Camp David to consider options for the future of the US war in Afghanistan as he nears a decision, but Bannon is not there -- and was not scheduled to be, based on a list of attendees the White House sent out Friday morning.
