"We don't need Muslims. We need smart, well-educated white people," says one of the voices on the call.
"I am a farmer and white nationalist," says another. "Support Donald Trump."
As CNN first reported Friday, the robocalls are bankrolled by William Johnson, a California attorney, through the American National Super PAC. Johnson is chairman of the American Freedom Party, a group designed to "represent the interests and issues of European-Americans," according to its website.
Johnson confirmed to The Huffington Post that he is responsible for the calls and said they went out to every landline number in New Hampshire.
"Donald Trump has a unique combination, politically, of populism with nationalistic sentiment," Johnson said. "He's forthright and doesn't back down."
The lawyer pointed to Trump's anti-immigrant, anti-Muslim positions as ones that drew his support. He also likes Trump's call for lower taxes for all workers, but wishes the real estate magnate was a stronger advocate for the environment and opposed U.S. intervention in foreign conflicts.
One of the men speaking on the robocall is Jared Taylor, who runs the "race-realism" publication American Renaissance. Taylor told HuffPost that he is a "white advocate," arguing that diversity is just a "source of tension."
"What would I like to see recognized is that it is perfectly natural, normal and healthy for people to prefer the company of people like themselves," Taylor said.
He also praised Trump's xenophobic remarks, claiming that Muslim immigration to the U.S. has led to only "terrible results."
"Most white people act the way I do," he said. "They just don't dare say so."
Trump's campaign didn't immediately return a request for comment, but campaign spokeswoman Hope Hicks had told CNN that the billionaire businessman has disavowed "all super PACs offering their support."
Johnson said he has had zero contact with Trump's campaign.
While he said he has received just a handful of positive responses to the phone messages -- more people have reached out to say they won't be supporting Trump -- Johnson plans to keep robocalling ahead of future primaries.
Editor's note: Donald Trump is a serial liar, rampant xenophobe, racist, misogynist, birther and bully who has repeatedly pledged to ban all Muslims -- 1.6 billion members of an entire religion -- from entering the U.S.
