Casino owners don’t like to operate in the sunlight and Sheldon Adelson is no different.

The Las Vegas Sands owner doesn’t want to discuss the reasons why he donated $5 million to PAC that is tied to Newt Gingrich. The billionaire casino mogul has turned down several media requests.

A source close to Adelson told CBS news that the casino owner doesn’t want anything in return for the $5 million donation. Another source told the New York Times that Adelson was merely helping a friend.

“His friend needed his help,” said a close associate of both men, who spoke on the condition of anonymity to avoid drawing Mr. Adelson’s ire. “It’s more than anything else a loyalty thing. And he believes strongly in his platform and in Newt’s candidacy.”

Gee, sounds like Adelson is as loyal as Lassie. Let’s get real: No one gives someone $5 million just because they like them. The ties between the two men go back years.

When he was House speaker, Gingrich helped Adelson combat union organizing efforts at his gaudy Venetian casino in Vegas. Gingrich also backed legislation in 1998 to preserve tax deductions beneficial to the industry, The Times reported. Adelson has donated millions to Gingrich in the past and let him use his corporate jet.

Hey, what are friends for.  Come to think of it, there is nothing like having a friend in the White House.

Adelson’s company is currently under federal investigation for possible violations of a federal anti-bribery law, relating to operations in Macau, the Chinese gambling district. The company said the investigation was prompted by allegations from a disgruntled former employee.
