Mitt Romney strikes back at critics of Bain record with new South Carolina ad

(FoxNews.com) - Mitt Romney struck back Friday at campaign trail critics who have gone after his record at private equity firm Bain Capital, as conservatives rallied to his defense and warned the infighting is bad for the Republican Party.

The frontrunning GOP presidential candidate launched a new TV ad in South Carolina that highlights major businesses that Bain Capital once supported, including Staples and Sports Authority.

"Mitt Romney helped create and ran a company that invested in struggling businesses, started new ones, and rebuilt old ones, creating thousands of jobs," the narrator in the ad says. "Those are the facts."
