David Duke Supports Trump, Urges White Supremacists to Volunteer for Campaign

Of the candidate on the trail who has been really going after Goldman Sachs, Duke said Sen. Bernie Sanders (I-Vt.) is "nothing more than a Jewish extremist himself."

He also advocated that young men join Trump's campaign to meet women or join a Democrats' group as a "manly male" to woo over members to supremacist ideology as an "infiltrator."

"The Trump campaign is an amazing opportunity for us," Duke said, stressing "how we can wrap up this nomination" and "build our movement" in the process.

White House press secretary Josh Earnest told reporters today that he hadn't seen Duke's comments and didn't have an immediate reaction.

White nationalists have made robocalls for Trump in early states, saying that the calls were not authorized by the Trump campaign. The white supremacist American National Super PAC began a robocall campaign in Vermont and Minnesota this week telling voters, “Don’t vote for a Cuban. Vote for Donald Trump.”

Before the Iowa caucuses, some voters received a robocall stating, "We don't need Muslims. We need smart, well-educated white people who will assimilate to our culture. Vote Trump."

Trump was asked about those calls on CNN last month.

"Nothing in this country shocks me," he said after the Iowa call was played for him on-air. "I would disavow it, but nothing in this country shocks me. People are angry. They're angry at what's going on. They're angry at the border. They're angry at the crime. They're angry at people coming in and shooting Kate in the back in California and San Francisco. They're angry when Jamiel Shaw shot in the face by an illegal immigrant. They're angry when the woman, the veteran, 65 years old is raped, sodomized, and killed by an illegal immigrant."

"And, they're very angry about it, and -- by the way, thousands of other cases like that. They're very angry about it. So, I would disavow that, but I will tell you people are extremely angry."
