Romney campaign manager Matt Rhoades issued a blistering statement in response.
“President Obama’s campaign hit a new low today when one of its senior advisers made a reckless and unsubstantiated charge to reporters about Mitt Romney that was so over the top that it calls into question the integrity of their entire campaign,” Rhoades said. “President Obama ought to apologize for the out-of-control behavior of his staff, which demeans the office he holds. Campaigns are supposed to be hard fought, but statements like those made by Stephanie Cutter belittle the process and the candidate on whose behalf she works.”
The challenge capped a frenzied and nasty day on the campaign trail.
