UPDATED: Not Enough Evidence Against Horne, Judge Rules

An Arizona administrative law judge says there's not enough evidence to conclude Republican Attorney General Tom Horne broke campaign finance law.

Judge Tammy Eigenheer issued her ruling Monday. She said prosecutors didn't prove Horne illegally coordinated campaign spending with an aide running an independent group during his 2010 election bid.

Yavapai County prosecutors say they produced enough evidence during a February civil hearing to show Horne and aide Kathleen Winn broke campaign-finance law by working together on outside ads targeting Horne's Democratic opponent.

They wanted Horne to repay $400,000 to donors and up to three times that amount in civil fines.

Horne and Winn's lawyers argued there's no evidence they broke the law. They also say an FBI agent committed perjury at the hearing but Eigenheer rejected that contention.
