The White House on Sunday attempted to clarify President Donald Trump’s comments on deadly weekend violence at a white supremacist demonstration in Charlottesville, Va., after his vague remarks on Saturday came under blistering criticism from Democrats and Republican alike.

An unnamed White House spokesperson said Sunday that Trump “condemns all forms of violence, bigotry, and hatred and of course that includes white supremacists, KKK, Neo-Nazi and all extremist groups.” The source refused to be named, despite the White House’s recent campaign to discredit journalists’ unnamed sources.

On Saturday, Trump did not explicitly condemn the white supremacists — some of whom were heavily armed and chanting Nazi slogans — saying instead blaming “hatred, bigotry and violence on many sides — on many sides.”

Trump Condemns ‘Many Sides’ of Charlottesville Violence

Heather Heyer, a 32-year-old paralegal, was killed and 19 others injured when a man with reported white supremacist ties drove into a crowd of counter-protesters in Charlottesville. Two Virginia state troopers who were monitoring the white-supremacist rally were also killed in a helicopter crash.

On Sunday morning, at least three top Trump advisers appeared on morning talk shows and defended his vague “many sides” remarks, though later in the day comments from Trump’s team became more explicit.

“There should be no place in society for racism, white supremacy and neo-nazis,” Ivanka Trump, the president’s daughter, tweeted Sunday.

National security adviser H.R. McMaster told NBC News’ “Meet the Press” on Sunday that Heyer’s death was an act of terrorism.

Earlier, a number of lawmakers from both sides of the aisle sharply criticized Trump for not taking a stronger stance.

Trump’s former communications director, Anthony Scaramucci, also criticized the president’s response, telling ABC News: “I think he needed to be much harsher as it related to the white supremacists and the nature of that.”

White supremacists appeared emboldened by Trump’s failure to explicitly condemn their actions. The neo-Nazi website Daily Stormer interpreted Trump’s remarks as tacit approval:

“Trump comments were good. He didn’t attack us. He just said the nation should come together. Nothing specific against us. He said that we need to study why people are so angry, and implied that there was hate … on both sides! So he implied the antifa are haters. There was virtually no counter-signaling of us at all. He said he loves us all.”
