Bannon, who recently resigned as chairman of Breitbart News, was named CEO of Donald Trump's presidential campaign in August 2016.
After days of silence amid withering criticism from his former colleagues and his largest benefactor, Bannon tried to make amends.
Trump himself said Wednesday that it "seems unlikely" that he'd give an interview in special counsel Robert Mueller's investigation into potential coordination between Russian Federation and the Trump campaign.
Bannon was named chief executive of the Trump campaign two and a half months before Election Day.
Mr Trump, although he had eventually supported Mr Moore's candidacy, later blamed Mr Bannon for the embarrassment.
Between Bannon raising the word "treasonous" around that now infamous meeting with Russians at Trump Tower, and reports of him effectively ridiculing his boss in that new book "Fire and Fury", the bro-fest between them is over. Mr. Bannon, he said, had "very little to do with our historic victory". Mr Bannon, a former investment banker turned Hollywood producer turned conservative activist, was at that time connected to Breitbart News, which he helped co-found.More news: Will triple talaq bill benefit the Muslim women?
After resuming his position at Breitbart, Bannon set out to challenge Republican incumbents deemed insufficiently loyal to the Trump administration.
Mr Trump and Mr Bannon have had a long and turbulent history. Burck already represents White House Counsel Don McGahn and former Chief of Staff Reince Priebus in the Mueller inquiry.
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.
Wednesday night, the White House released an official statement explicitly saying that a proposed amendment that would weaken the NSA's power would undermine "the useful role FISA's Section 702 authority plays in protecting American lives".
Trump said "we'll see what happens" when asked if he'd provide an interview to Mueller's team.
