The report shows receipts of $2.1 million. The PAC's spending reports, which by contrast cover the month of January, already show the same PAC spending nearly $9 million so far.
Even before the Adelsons contributed $10 million, three of his family members had already plunked down $1 million in seed
money for the group.
The PAC reported a $500,000 contribution from one of Adelson's step-daughters, Sivian Ochshorn, and another $250,000 from another step-daughter, Yasmin Lukatz. Another family member, Oren Lukatz, gave an additional $250,000. All three listed themselves as "self employed" at 3355 Las Vegas Blvd. in Las Vegas, the address of Adelson's Las Vegas Sands Hotel, and gave the money the same day, Dec. 22.
Also giving a big check to the Gingrich Super PAC was Harold Simmons, the chairman of Contran Corporation, a Texas firm that owns a controversial radioactive waste dump. He had already given two checks totalling $1 million to the Rick Perry Super PAC.
The Associated Press described Adelson's interest in Gingrich in this way: "Adelson is an extreme conservative and staunch backer of right-wing Israeli politicians. Gingrich has held policy positions that would match Adelson's regarding U.S.-Israeli relations, including a pledge to issue a directive on his first day as president to relocate U.S. embassy from Tel Aviv to Jerusalem. That would enrage Palestinians who demand that part of Jerusalem be their capital in any future two-state solution."

Super PACS are known to the Federal Election Commission as independent committees, because they are forbidden to coordinate their activities with campaigns. Outside the limits of campaign finance laws, Super PACs may raise unlimited sums of money from corporations, unions, associations and individuals. They can use that money to advocate for or against political candidates.
