As Newt Gingrich begins to distance himself from the "King of Bain" ads run by Winning Our Future, the SuperPAC has issued an open letter to Mitt Romney asking for help in addressing the alleged factual discrepancies.

The open letter, dated Friday, acknowledges the Washington Post fact checker rating of four Pinnochios for "King of Bain" but says the critique hinges on whether Romney actually severed all ties with Bain Capital in 1999, not whether "any of the terrible things portrayed" ever happened.

"We reviewed the raw footage, the transcripts, we one hundred percent stand by (King of Bain)," Gregg Phillips, managing director of Winning our Future, told Fox News.

In the letter, Phillips calls on Romney to answer the following questions:

1. When did you leave Bain for good -- full time or part time?2. When did you relinquish controlling interest in Bain, any Bain projects or Bain funds?3. When did you resign as the CEO?4. When was the last Bain document submitted to the government denoting you as an executive at Bain?5. When did you receive the final check from Bain for any investment in which you had and interest?

The Romney campaign scoffed at the letter. "It is sad to see just how desperate Speaker Gingrich and his allies have become as his campaign continues to flounder," said Romney spokesperson Andrea Saul. "It is a matter of public record that Mitt Romney left Bain Capital in 1999 to run the Olympic Games in Salt Lake City. At that time, he gave up all management control and operational responsibility over the firm and its investments." Phillips says his SuperPAC will continue to run the Bain ads until Romney provides hard evidence that he had no investment or control over Bain Capital after 1999. Additionally, starting Sunday, Winning Our Future will begin airing two new ads attacking Romney: the first ad questions Romney's electability by calling him a "RINO," a Republican in Name Only, and the second ad accuses him of "fuzzy math" in counting how many jobs he created at Bain.
