Miriam Adelson, the wife of the gambling mogul whose $5 million donation helped make Newt Gingrich competitive in South Carolina, has told her banker to wire Gingrich’s super PAC another $5 million on Monday, a source close to Adelson said.

Adelson, 66, is a practicing physician who runs the Dr. Mirriam Adelson and Sheldon G. Adelson Clinic for Drug Abuse and Treatment in Las Vegas and Tel Aviv. Sheldon Adelson, 78, is the CEO and primary owner of Las Vegas Sands,

The Adelsons’ earlier new life to Gingrich’s campaign when he made a $5 million on Jan. 6 to the Winning Our Future Political Action Committee, a so-called Super PAC that can accept unlimited donations.

A source in Las Vegas said the money should arrive via wire transfer on Tuesday at Winning Our Future’s bank account. The new $5 million pledge was first reported by Jon Ralston, a longtime Las Vegas Sun columnist who covers the gambling industry.

The Adelsons met Gingrich when he was speaker of the House in mid-1990s, and his support for a strong Israel. Mirriam Adelson was born in Israel and Sheldon Adelson is the son of Lithuanian Jewish immigrants.
