PHOENIX (AP) _ An FBI agent who investigated allegations that Arizona Attorney General Tom Horne broke state campaign finance laws has begun testifying in a civil case that could cost Horne more than a million in fines and donor repayments.
Horne and an aide are facing civil allegations of violating campaign finance laws during his 2010 election run.
Horne and Kathleen Winn deny illegally coordinating spending while she ran an independent committee called Business Leaders for Arizona.
Yavapai County Attorney Sheila Polk brought the charges in October. An Arizona Office of Administrative Hearings judge began hearing the case Monday.
An FBI agent testified about calls and emails between Horne, Winn and her campaign consultant.
Polk ordered Horne to return nearly $400,000 to donors and is seeking three times that amount in fines.
