Attorney General Mike Hunter has launched a new campaign ad that is harshly critical of opponent Gentner Drummond.

"Uncaring. Unethical. Unfit to be our attorney general," an announcer states at the end of the 30-second ad that targets Drummond's legal practice.

The spot began airing Friday and will continue for weeks at a total cost of about $250,000, Hunter's campaign said.

Drummond responded Monday, issuing a news release that called the ad false and misleading.
