Greer, South Carolina (CNN) - An outside group supporting Mitt Romney unleashed a new attack on former House Speaker Newt Gingrich as the GOP nomination battle grew increasingly heated.
The Restore our Future PAC said it will air a television ad called "Desperate" in the early voting states of South Carolina and Florida, as part of an already announced multi-million dollar ad buy.

The heavily stylized ad announced: "Newt attacks because he has more baggage than the airlines" and hit the former House speaker for ethics violations and a payment from mortgage giant Freddie Mac.
The spot also said Gingrich sponsored a bill with former House Speaker Nancy Pelosi that in part would have funded China's one-child policy.
The offensive comes as Republicans increasingly predict a divisive primary battle among Republican candidates in South Carolina, where voters head to the polls Jan. 21.
Team Gingrich did not immediately respond to a request for comment.
