Attorney General Tom Horne denied allegations that he violated campaign laws in 2010 and accused the prosecutor who made them of filing a complaint because he knew he was about to lose his job.

In an email on Monday evening, Horne spokeswoman Amy Rezzonico said the attorney general did not illegally collaborate with Kathleen Winn, the chairwoman of a pro-Horne independent expenditure that spent more than a half-million dollars on attack ads against his Democratic opponent.

Federal authorities are investigating Attorney General Tom Horne over allegations that he 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.

The complaint, filed with the Arizona Secretary of State’s Office, also alleges that Horne rewarded the chairwoman of the campaign group with a high-paying job at the Attorney General’s Office.

James Keppel, the head of the criminal division of the Arizona Attorney General’s Office, resigned his post after more than a year with the office.
