The Democratic National Committee is calling on Republican Norm Coleman to concede the Minnesota Senate contest to Democrat Norm Coleman in a new radio ad it is airing in Minneapolis/St. Paul.

A three judge panel ruled against Coleman earlier this week, effectively naming Democrat Al Franken the winner. Coleman has vowed to appeal the decision to the Minnesota Supreme Court.

The ad says "enough is enough" and urges listeners to "call Norm Coleman...[and] tell him it is time to concede."

The ad comes after DNC Chairman Tim Kaine also called on Coleman to concede on Tuesday.
