Steve Bannon has returned to Breitbart News after he was ousted as President Donald Trump's chief strategist.
Charlie Spiering, the White House correspondent for Breitbart, tweeted that Mr Bannon returned as executive chairman and chaired their evening editorial meeting.
Breitbart also ran a story on Mr Bannon's return.
"The populist-nationalist movement got a lot stronger today," said Breitbart News editor-in-chief Alex Marlow.
"Breitbart gained an executive chairman with his finger on the pulse of the Trump agenda."
The move had been widely expected.
Breitbart already has been taking aim at some of Mr Trump's advisers with whom Mr Bannon clashed, including the president's economic adviser Gary Cohn.
Mr Cohn, Jared Kushner, Ivanka Trump and others are viewed as moderates and even Democrats by Mr Bannon, determined to move Mr Trump's agenda away from the kind of populism and nationalism he favours.
Earlier on Friday, Mr Bannon told Joshua Green of Bloomberg News that "if there's any confusion out there, let me clear it up: I'm leaving the White House and going to war for Mr Trump against his opponents - on Capitol Hill, in the media, and in corporate America."
Mr Bannon served as executive chairman of Breitbart since shortly after founder Andrew Breitbart's death in 2012. Mr Trump tapped him as his campaign chief executive in August, 2016.
Mr Bannon's appointment as chief strategist was heavily criticised by Martin O'Malley, a Democrat who ran for President last year. In New Zealand, he told The Nation Mr Bannon was "ideological and racist" and had no place in the White House.
