When asked by CNN's Jake Tapper on Sunday about David Duke and the KKK supporting his candidacy, Donald Trump passed on refuting them. "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." When Tapper said he was specifically talking about the KKK, Trump continued saying, "I have to look at the group. I mean, I don't know what group you're talking about." He then declared, "You wouldn't want me to condemn a group that I know nothing about. I'd have to look. If you would send me a list of the groups, I will do research on them and certainly I would disavow if I thought there was something wrong. You may have groups in there that are totally fine -- it would be very unfair. So give me a list of the groups and I'll let you know."
