Washington (CNN) - Billionaire casino mogul Sheldon Adelson did not direct the independent Super PAC supporting Newt Gingrich on how it should spend the five million dollars he donated to it last week, a source close to Adelson told CNN.
"It was a donation with no instruction," the source said adding Adelson "gave no preconditions."

That contribution gave a much needed boost to the PAC, Winning Our Future, allowing it to make a major purchase of ad time in South Carolina, a state Gingrich has said he must win to keep his presidential hopes alive. Super PACs supporting candidates and their campaigns are not allowed by law to coordinate their activities.
The PAC this week released a scathing movie online criticizing Mitt Romney's role in the venture capital firm Bain Capital and chronicling how some of the companies it took over later filed bankruptcy. It calls him a "corporate raider" and features interviews with workers from some of the companies closed after Bain took them over.
Winning Our Future went up on television Thursday with a paid commercial in South Carolina featuring a portion of that movie, according to the group. The PAC also put up an ad earlier this week in the state touting the former House speaker as an exceptional leader.
The PAC said the leadership ad as well as one dealing with the Bain issue will both continue to air.
Supporters of Adelson, who has not commented publicly on the donation, rejected the idea that his contribution could be seen as anti-business.
"Criticisms of Aldeson being anti-capitalism are ridiculous," the source close to Adelson said. "He made a donation to help his friend.
Adelson, a long-time friend of Gingrich, previously contributed to Gingrich-run organizations.
The source also said the gambling magnate had not seen any of the ads from the super PAC and does not have an opinion of them.
"He is not involved in the tactics or the strategy of the super PAC in any way," the source said.
Gingrich and his allies have come under criticism from conservatives for pushing a message that could be seen as criticizing capitalism and exposing rifts that the President Barack Obama's re-election team could take advantage of if Romney captures the Republican nomination.
The movie has come under criticism by some non-partisan fact checkers for not presenting the full story regarding the impact of Bain. The Romney campaign has distributed articles detailing that to members of the press.
Asked for reaction to the stories, the PAC's spokesman Rick Tyler said "We've apparently embarrassed the national press corps by doing their job for them."
