Steve King, the Republican congressman who represents the northwestern part of Iowa, is a white nationalist.

King has said he doesn’t want Muslims working in Iowa meatpacking plants. He has lied about how much crime undocumented immigrants commit. He has said that Dreamers — undocumented immigrants who came to the United States as young children — have calves the size of cantaloupes.

He has cultivated ties with European white supremacists. He has decried “cultural suicide by demographic transformation.” He said that “Leftists” consider “everyone who lacks melanin” to be racist. He has approvingly retweeted a woman who called interracial marriage worse than murder and who said the TV show “Seinfeld” taught her to dislike Jews.
