TAPPER: Will you unequivocally condemn David Duke and say that you don't want his vote or that of other white supremacists in this election?

TRUMP: Well, just so you understand, I don't know anything about David Duke, okay? I don't know anything about what you're even talking about with white supremacy or white supremacists. So, I don't know. I don't know, did he endorse me or what's going on, because, you know, I know nothing about David Duke. I know nothing about white supremacists. And so you're asking me a question that I'm supposed to be talking about people that I know nothing about.

TAPPER: But I guess the question from the Anti-Defamation League is, even if you don't know about their endorsement, there are these groups and individuals endorsing you. Would you just say unequivocally you condemn them and you don't want their support?
