Democratic presidential candidates Beto O'Rourke and Sen. Elizabeth Warren both called President Trump a "white supremacist" in separate interviews on Wednesday.

Details: Warren told the New York Times Trump gave white supremacists aid and comfort. "He’s done the wink and a nod," she said. "He has talked about white supremacists as fine people. He’s done everything he can to stir up racial conflict and hatred in this country." O'Rourke told MSNBC Trump made it "very clear" that he's a white supremacist.

Why it matters: Several 2020 candidates have denounced Trump for racism, but the comments of Warren and O'Rourke mark the strongest condemnation yet of Trump and his divisive rhetoric and anti-immigration policies.

While former Vice President Joe Biden has not called Trump a white supremacist, he did say earlier Wednesday that the president "has fanned the flames of white supremacy in this nation."
