“You can’t condemn the violence unless you condemn those people who continue to argue the election was not real, that it’s being stolen, that all the malarkey that’s being put out there to undermine democracy,” he said.

The president spoke to reporters about the attack at a polling center in Delaware, where he voted early with his granddaughter Natalie Biden.

“The talk has to stop. That’s the problem,” he said. “That’s the problem.”

Biden appeared annoyed the Republicans were condemning political violence without condemning some of the rhetoric coming from their colleagues.

“You can’t just say, ‘I feel badly about the violence; we condemn it,'” he said. “Condemn what produces the violence, and this talk produces the violence.”

He blamed Republican political rhetoric for inspiring mentally ill people to violence.
