Former Breitbart executive Steve Bannon is the latest casualty of White House power struggles. US President Donald Trump has fired his chief strategist at the urging of his newly appointed chief of staff, retired General John Kelly, multiple news outlets reported.

Bannon joined the Trump presidential campaign as chief executive in August 2016, and went on to become President Trump's "chief strategist," a position created specifically for him, while former GOP chairman Reince Priebus was appointed chief of staff.

The president's critics have called for Bannon's removal almost from the very beginning, accusing the former Breitbart News chief executive of being a racist, white supremacist, and Islamophobe.

Bannon is a former US Navy officer who worked at Goldman Sachs in the 1980s and was one of the founders of Breitbart, a conservative news outlet.

Earlier this week, when reporters asked Trump about Bannon and his alleged support for white nationalism, Trump called him a friend.

"He is not a racist, I can tell you that. He's a good person," Trump said at a press conference on Tuesday. "I think the press treats him very unfairly."

It was the same phrasing he used about his former national security adviser, General Michael Flynn, who resigned under media pressure in February.

On Wednesday, the left-leaning publication American Prospect published an interview in which Bannon talked about the US "trade war" with China and dismissed the prospects of military confrontation with North Korea. Bannon also described white nationalists as "losers" and "a fringe element" that needs to be crushed.

Bannon is the latest casualty of the purge of Trump's senior staff that began in late July with the departure of press secretary Sean Spicer, followed by Priebus and communications director Anthony Scaramucci, who was on the job for only 11 days. Kelly, a retired Marine who previously headed the Department of Homeland Security, was appointed the new chief of staff to "restore order," according to reporters covering the White House.
