FBI investigating Tom Horne for campaign violations Arizona Capitol Times

Federal authorities are investigating allegations that Attorney General Tom Horne illegally collaborated with an independent expenditure committee that spent more than a half-million dollars on negative ads against his Democratic opponent in 2010, the Arizona Capitol Times has learned.

A complaint filed in February by a prosecutor in Horne’s own office – and a onetime political ally of Horne – alleges that the attorney general collaborated with an independent expenditure called Business Leaders for Arizona, which received $115,000 from Horne’s brother-in-law in California.
