Chris Simcox's wife is seeking a divorce and alleges in court documents that he twice brandished a gun and threatened to shoot his family in late 2009 - four years after he helped found the Minuteman movement that drew thousands of anti-illegal immigration activists to patrol the border.
Simcox worked recently as an adviser to J.D. Hayworth, who is challenging Sen. John McCain in Arizona's Republican primary. A Hayworth spokesman says Simcox is no longer affiliated with the campaign.
A judge in Phoenix ordered Simcox to surrender his guns and stay away from his family.
