(CNN) – Newt Gingrich's campaign sent letters to certain TV stations Friday warning them against airing a commercial paid for by a super PAC supporting Mitt Romney.
According to the letter, the campaign claims the ad is "fundamentally NOT TRUE."

Produced by the group Restore Our Future, the commercial is set to air in Georgia, a state Gingrich formerly represented as congressman, as well as other Super Tuesday states.
The spot claims Gingrich co-sponsored a 1989 bill with then-Rep. Nancy Pelosi "that would have given $60 million a year to a U.N. program supporting China's brutal one-child policy."
But the former House speaker claimed the ad is "unequivocally false."
Titled "Global Warming Prevention Act," the bill at issue was introduced while Gingrich was still a congressman but never passed. Along with supporting stricter fuel standards for cars and alternative energy, the legislation also called for sending money to developing countries to promote clean energy standards.
The bill proposed sending money to the U.N. Population Fund, some of which would go to China, but one section in the bill stipulated that no funds should go towards backing involuntary sterilization, abortion, or family planning coercion.
And while it's true Gingrich co-sponsored the legislation with Pelosi, there were a total of 144 House members who also sponsored the bill, according to PolitiFact.
On Friday, the campaign demanded the TV stations immediately refuse or cease airing the ads and "refrain from broadcasting their content until such time as the libelous statements have been removed."
The letter warned if the stations broadcast the ad after receiving the letter, they will be knowingly airing a "false statement" and potentially liable for defamatory communication.
Last month, Team Gingrich made a similar move and called on TV stations to ban another ad by Restore Our Future that claimed Gingrich was fined for an ethics violation during his tenure as speaker. Gingrich maintained he was forced to pay a "reimbursement," not a fine.
The candidate has long pushed back against negative ads from the super PAC, as well as Romney's campaign. Since placing second in Florida's primary last month, Gingrich has largely attributed negative ads for his recent decline in the polls and disappointing finishes in other contests.
