Loss of his media perch jeopardizes Bannon's campaign to remake the Republican Party by fielding Trump-allied candidates to challenge incumbent lawmakers. For months, Trump allowed Bannon to conduct open war from inside the White House against established party leaders, incumbent lawmakers and other heavyweights Bannon believed were undermining Trump's populist revolution.
The former chief strategist, who was ousted as Breitbart News chief over his feud with Trump, could also potentially tell investigators whether Trump fired FBI director James Comey in hopes of stopping or stalling the Justice Department investigation later taken up by Mueller. In the book, Bannon described Trump's son-in-law Jared Kushner's meeting with a Russian lawyer as "treasonous" and "unpatriotic".
Bannon was said to have kept in touch with Trump after leaving the White House, but Trump last week publicly rebuked Bannon for comments he made in Michael Wolff's new book "Fire and Fury". It also covers only Bannon's role on Trump's campaign, as opposed to events that occurred during the presidential transition or while Bannon served as a top aide to Trump in the White House.
Forty-six percent of Republicans who were surveyed registered an unfavorable view of Bannon, a 17-percent increase from the last poll, taken December 14-18.More news: Armed robbers loot jewellery worth millions in Paris
Bannon attempted to walk back from the remarks, telling the Axios news website that "Donald Trump Jr.is both a patriot and a good man", but the closest he came to an apology was regretting the timing of his response. In a statement, Trump said Bannon has nothing to do with his presidency and has "lost his mind". He also reportedly represents White House Counsel Donald McGahn and former White House chief of staff Reince Priebus in relation to the Russian Federation investigation.
Bannon on Sunday released a statement expressing regret over the comments.
But Trump left the door open when asked if the relationship was over permanently.
The President pointed to his initial success during the campaign, prior to Bannon joining the team.
