Right-wing commentator Jesse Lee Peterson appeared on a white nationalist’s podcast last week, telling the host that white people in America need to get married and “have a truckload of white children” because “unless white people take over, it’s over for America.”

Peterson has ties to Fox News host Sean Hannity and has appeared at events with right-wing media personalities including Mike Cernovich. He’s made several appearances on Fox News and he currently hosts a show on Newsmax TV.

Peterson gave an interview to white nationalist podcast host Jean-Francois Gariépy on January 4, during which the duo discussed declining birthrates among white people in the United States. Peterson has appeared on other far-right podcasts, where he’s largely sympathized with the hosts. Peterson frequently claims that racism never existed and that people of color have been undermining America since the Civil Rights era.

Gariépy and Peterson agreed with the claim that non-white people immigrating into the U.S. is making it harder for white people to live in America, prompting Peterson to assert that the United States needs “to close the back door and the front door in this country and in Europe and clean up the mess and if you decide you want to let people of color in again, maybe you can be real selective—like they did in the good old days—about who you let it.”

“White people need to get married and have a truckload of white children and teach them on the right way to go so they can help save America and Europe because it’s not going to be saved by the people of color and will be destroyed,” Peterson said.

Gariépy asked Peterson what he thought the political solution to non-white people entering the country should be, whether it is separation, education, or something else entirely. Peterson responded by telling him his plan to buy land in a white-person space colony.

“The good white folks are going to go to moon or somewhere else and they’re going to create another country, so I’m saving up my money so when white people build a spaceship and go out into space and build another country, I’m going to go with them and I’m going to be first to buy some of the land because I know the land is going to go up really fast,” Peterson said. “But unless white people take over, it’s over for America.”
