The chief White House strategist Steve Bannon has attacked white nationalists as “clowns” as the fallout from violent protests in Charlottesville continues.
Mr Bannon once headed the far-right Breitbart News, seen as both a major channel for nationalism and key in helping Donald Trump win election.
But Mr Bannon told Prospect magazine: “Ethno-nationalism – it’s losers”.
Questions surround Mr Bannon’s future, with President Trump refusing to say if he had confidence in him.
Mr Trump has reportedly been urged to fire Mr Bannon, who in his role has enjoyed direct access to the president and whose influence has been seen in decisions like the US withdrawing from the Paris climate accord.
At a news conference this week Mr Trump would only say “we’ll see” when it came to Mr Bannon’s future.
Mr Trump is under fire for his response to the clashes between far-right and counter protesters in Charlottesville, Virginia, in which he blamed “both sides” for the violence.
The rally, attended by neo-Nazis and white supremacists, was in protest of the removal of a statue of Robert E Lee, a general who fought for the pro-slavery Confederacy during the US Civil War.
A memorial was held on Wednesday for Heather Heyer, a 32-year-old woman killed when a suspected far-right sympathiser drove a car into a crowd of counter-protesters.
In his interview, Mr Bannon was asked if there was a connection between the economic nationalism that he supports and the white nationalism seen in Charlottesville.
“Ethno-nationalism – it’s losers,” he said. “It’s a fringe element. I think the media plays it up too much, and we gotta help crush it, you know, uh, help crush it more.”
“These guys are a collection of clowns,” he added.
Mr Bannon has distanced himself from “ethno-nationalism” before, telling the New York Times his interest in nationalism stems from wanting to curb the negative effects of globalisation.
North Korea: Despite Donald Trump threatening North Korea with “fire and fury”, in his interview Mr Bannon said there was no military solution to the crisis over the Pyongyang’s nuclear programme.
“Until somebody solves the part of the equation that shows me that 10 million people in Seoul don’t die in the first 30 minutes from conventional weapons, I don’t know what you’re talking about, there’s no military solution here, they got us,” he said.
China: Mr Bannon said if anything North Korea was just a “sideshow” to the real challenge the US is facing – “economic war” with China.
“If we continue to lose it, we’re five years away, I think, ten years at the most, of hitting an inflection point from which we’ll never be able to recover,” he said, adding that the US intended to challenge China over intellectual property rights, and iron and steel dumping.
White House infighting: He admitted he was facing an internal battle for the administration to take a firmer line on Chinese trade, but said opponents were “wetting themselves”.
