At today's press conference announcing New Jersey governor Chris Christie's endorsement, Donald Trump was asked about another endorsement he received recently from white supremacist David Duke.

"Voting for these people, voting against Donald Trump at this point is really treason to your heritage," the former KKK Grand Wizard said on his radio program Wednesday. "I'm not saying I endorse everything about Trump, in fact I haven't formally endorsed him. But I do support his candidacy, and I support voting for him as a strategic action. I hope he does everything we hope he will do."

The comments about heritage are clearly alluding to the fact that Trump's two top competitors, Ted Cruz and Marco Rubio, are both Hispanic.

Duke also exhorted his followers to volunteer for Trump and suggested that his campaign was already staffed with racists.

"And I am telling you that it is your job now to get active. Get off your duff. Get off your rear end that's getting fatter and fatter for many of you every day on your chairs. When this show's over, go out, call the Republican party, but call Donald Trump's headquarters, volunteer," he said. "They're screaming for volunteers. Go in there, you're gonna meet people who are going to have the same kind of mind-set that you have."

Trump responded to being asked about the comments by telling the press, "I didn't even know he endorsed me. David Duke he endorsed me, OK? I disavow. OK?"
