"The Sunday uproar started when Trump was asked by Tapper whether he would disavow Duke and other white supremacist groups that are supporting his campaign.

"Just so you understand, I don't know anything about David Duke, OK?" Trump said.

"Trump was pressed three times on whether he'd distance himself from the Ku Klux Klan -- but never mentioned the group in his answers.

"I don't know anything about what you're even talking about with white supremacy or white supremacists," he said. "So I don't know. I don't know -- did he endorse me, or what's going on? Because I know nothing about David Duke; I know nothing about white supremacists."
