WASHINGTON, D.C. — (MCT) The billionaire casino mogul whose massive donations to a super PAC have kept alive the presidential ambitions of Newt Gingrich is finally speaking publicly about his role in this presidential race.

In a cover story interview with Forbes magazine, a defiant Sheldon Adelson suggested he might give as much as “$100 million to Gingrich.” He dismissed as “unfair” speculation that he has been trying to buy the presidential election, saying people who think that “are either jealous or professional critics.”

The remarks came as Winning Our Future, the super PAC to which Adelson and his wife publicly wired $10 million last month, submitted financial forms revealing where it had received its money and how the money was being spent. The forms show that the Adelsons have almost single-handedly financed the committee, which is credited with helping Gingrich win in South Carolina and with keeping his campaign afloat in Florida, where he placed second behind Mitt Romney.
