Arizona Rep. Paul Gosar’s family continued criticizing his conspiracy theories with his brother calling the lawmaker “an embarrassment.”

Gosar’s brother David criticized the congressman for espousing conspiracy theories about racial violence in Charlottesville, Virginia and that progressive megadonor George Soros was behind the operation, Phoenix New Times reported.

“At what point do you draw the line in your family,” David Gosar asked.

Earlier this month, Gosar was interviewed by Vice News and said that “Unite the Right” rally in Charlottesville in August was a false flag operation and speculated that Soros backed organizers.

Gosar also said that Soros, who is Jewish, turned in “his own people to the Nazis” during the Holocaust.
