Republican presidential candidate Donald Trump is getting some help that could backfire on him. Iowa voters are getting automated "robocalls" from a white nationalist Political Action Committee (PAC) urging them to vote for Trump, reports Talking Points Memo.

"I urge you to vote for Donald Trump because he is the one candidate who points out that we should accept immigrants who are good for America," Jared Taylor says on the automated call, paid for by the American National Super PAC. "We don't need Muslims. We need smart, well-educated white people who will assimilate to our culture. Vote Trump."

Taylor is also a spokesman for the Council of Conservative Citizens, a group cited in a racist manifesto written by South Carolina shooter Dylann Roof, who shot to death nine parishioners in a rampage in a black Charleston church in June.

Taylor is also the founder of the white supremacist magazine American Renaissance. The robocalls include endorsements from conservative Christian talk show host Reverend Ronald Tan and William Johnson, leader of the white nationalist American Freedom Party. The party has issued a press release labelling Trump the "great white hope."

The party is also putting forward its own presidential candidate, Bob Whitaker, whose slogan is: "Diversity is a code word for white genocide." Whitaker said he supports Johnson's work for Trump.
