Attorney General opposes polygamists in northern Arizona, civil unions in southern Arizona
Arizona Attorney General Tom Horne is planning to file a lawsuit challenging the city of Bisbee's new civil union ordinance. He's also continuing efforts to challenge marshals in the polygamous community of Colorado City.
Horne tells Steve Goldstein that he's not opposed to civil unions but says the move by Bisbee would create problems.
Horne also decried Maricopa County Attorney Bill Montgomery's attempts to make him pay for alleged campaign finance violations. Horne continues to assert that he didn't violate state law.
