A wealthy supporter of Newt Gingrich will donate $5 million to a “super PAC” supporting his candidacy, providing a significant infusion of cash to the group as it seeks to defend Mr. Gingrich in Florida ahead of next week’s Republican primary, a person with knowledge of the contribution said on Monday.

The supporter, Dr. Miriam Adelson, is the wife of Sheldon Adelson, a longtime Gingrich friend and conservative ally who contributed $5 million to the super PAC, Winning Our Future, earlier this month. The couple has now given a total of at least $10 million to Winning Our Future.

News of the contribution was reported in a Twitter message on Monday evening by Jon Ralston, a columnist for The Las Vegas Sun.

While Mr. Adelson’s $5 million dollars financed a heavy barrage of negative advertisements attacking Mitt Romney for his record at Bain Capital, the private equity firm, the fresh contribution may be used in a different way. The person with knowledge of the contribution said, Dr. Adelson “asked the super PAC to use the contribution to continue the pro-Newt message.”
