Sean Reyes, in his suit filed Friday in 3rd District Court, contends Swallow, his campaign members and the Nevada-based "super" PAC It's Now or Never "worked in concert" to damage his reputation.
In a copyright story, the Deseret News reports the ads focus on an ethical question dealing with Reyes campaign fundraising that has been investigated and dismissed, and a 1993 incident of alleged road rage.
Swallow, the chief deputy for Attorney General Mark Shurtleff, calls the suit "frivolous" and says "desperate candidates do desperate things."
Documents show the Nevada-based political action committee has spent $140,000 in Utah in opposition to Reyes.
