During the first of three planned presidential debates, President Donald Trump on Tuesday refused to condemn white supremacy.

“Are you willing tonight to condemn white supremacists and groups to say they need to stand down and not add to the violence and number of the cities as we saw in Kenosha and as we’ve seen in Portland?” the debate’s moderator, Fox News host Chris Wallace asked.

Wallace noted that Democratic nominee Joe Biden attributed his candidacy to Trump’s comments that there were “very fine” people on both sides at a 2017 Unite the Right rally and counterprotest in Charlottesville that caused one woman to be killed.

“Sure. I’m willing to do that,” Trump answered but quickly added: “Almost everything I see is from the left-wing. Not from the right-wing.”

When Wallace pressed again for a clear condemnation, Trump asked, “What do you want to call them?”

“White supremacists,” Wallace replied.

“Proud Boys — stand back and stand by,” he said, seemingly addressing the far-right group. “But I’ll tell you what. I’ll tell you what. Somebody has to do something about Antifa and the left. This is not a right-wing problem. This is left-wing.”

Jason Miller, a senior adviser to the Trump campaign, said that Trump’s comments were “very clear he wants them to knock it off,” though Trump has not provided that clarification himself.

Proud Boys members quickly interpreted the comments as praise, calling the remarks “historic” in private social media channels, the New York Times reported.

According to the Times, a member said they were already seeing an uptick in “new recruits.”

The Proud Boys, a group founded in 2016 that describes itself as “a pro-Western fraternal organization for men” is classified as a hate group by the Southern Poverty Law Center and “hard-core white supremacists” by the Anti-Defamation League.
