Trump dodges on David Duke question: ' I know nothing about white supremacists'
Republican presidential front-runner Donald Trump avoided a question on Sunday morning about whether he'd condemn the racism of David Duke.
"I don't know anything about David Duke," he said Sunday morning on CNN's "State of the Union."
"I don't know anything about what you're even talking about with white supremacy or white supremacists," he added.
"I know nothing about white supremacists."
Duke, a white nationalist and former Ku Klux Klan grand wizard, last week told listeners of his radio show that voting against Trump would be "treason to your heritage." He encouraged his audience to vote and volunteer for the front-runner, saying they would meet people with "the same kind of mindset that you have."
The Anti-Defamation League called on Trump to "distance" himself from Duke and other white supremacists and "publicly condemn their racism."
But Trump said on Sunday that he knows nothing about Duke or white supremacists.
"You're asking me a question that I'm supposed to be talking about people that I know nothing about," he said, when asked if he would condemn Duke.
He said he would do research on the "groups" in question and would then decide if he would condemn them.
"I have to look at the group. I don't know what group you're talking about," he said. "You wouldn't want me to condemn a group that I know nothing about.
"I have to look."
In 2000, Trump called Duke "a Klansman" when the businessman decided to end his exploration of a run for president, according to The New York Times.
"The Reform Party now includes a Klansman, Mr. Duke," Trump said in a statement. "This is not company I wish to keep."
