Paul Gosar is the oldest of 10 children. His campaign did not respond to a request for comment.

Gosar has a long history of controversial remarks and actions. He promoted the conspiracy theory that the white supremacists’ rally in Charlottesville, Virginia, last year was a plot by the left financed by Democratic megadonor George Soros, who Gosar said “turned in his own people to the Nazis.”

In July, Gosar spoke in London at a rally for an anti-Muslim activist. He is also one of the staunchest opponents of legal rights for undocumented “Dreamers” in Congress.
