And the Romney campaign proceeds to dig itself deeper:

Romney Campaign Calls On Obama To Apologize For Staffer’s Remarks

Mitt Romney’s campaign manager Matt Rhoades issued a scorching statement Thursday calling on President Obama to apologize for top aide Stephanie Cutter’s suggestion that the ex-governor either lied or committed a felony regarding his tenure at Bain.

Rhoades’s statement:

“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. 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.”
