Trump named Bannon, the former chairman of the conservative news website Breitbart News, as his campaign chief in August 2016. After his inauguration, Trump appointed Bannon to fill the newly created position of White House chief strategist.
He left the Trump administration in August 2017, almost exactly one year after joining Trump’s presidential campaign.

Days before his exit, Bannon faced scrutiny for an interview he did with the liberal magazine The American Prospect, contradicting the president's warnings to North Korea of "fire and fury" in response to threats. Tension between the pair intensified last week after Bannon was quoted in journalist Michael Wolff's controversial tell-all book "Fire and Fury: Inside the Trump White House."

Bannon told Wolff he thought a meeting set up by the president’s son, Donald Trump Jr., with Russian lawyer Natalia Veselnitskaya and others in June 2016 was “treasonous” and “unpatriotic.” Trump slammed Bannon in a statement after the comments were made public, saying, “When he was fired, he not only lost his job, he lost his mind.”
Bannon later apologized for the comments.
