FRANKFORT — The Kentucky Democratic Party filed a complaint Friday with the state alleging that Republican gubernatorial nominee David Williams has illegally coordinated and cooperated with his father-in-law, Terry Stephens, and an outside political group that Stephens is financing.

Stephens has acknowledged being the sole contributor to Restoring America, which has spent $1.365 million on television ads that criticize Democratic Gov. Steve Beshear and compliment Williams.

A Franklin Circuit Court judge ruled last week that Restoring America violated the law by trying to hide the names of its donors.

In Friday's complaint, Democratic Party chairman Dan Logsdon said that Stephens hosted a fund-raiser at his home Sept. 13 that was attended by the leadership of the Williams-Farmer campaign. Seven days later, Restoring America and Restoring America Inc. were incorporated and funded, and they were on the air six days later with at least four television ads, Logsdon said.

The ads were produced by an Ohio firm that Williams was known to admire, Logsdon alleged.

Williams and Stephens have denied wrongdoing.
