FRANKFORT, Ky. (AP) -- Franklin County Circuit Judge Thomas Wingate granted the restraining order on Monday at the request of the Kentucky Democratic Party, citing "an illegal attempt" by Restoring America to influence the outcome of the general election.
The group has been running TV and radio ads attacking Beshear and supporting his Republican challenger, state Senate President David Williams.
Wingate said in his order that Restoring America has hidden the identities of donors who have given $1.3 million to pay for the ads.
Restoring America reported to the Kentucky Registry of Election Finance last week that it had gotten its money from an affiliated group called Restoring America Inc.
