Sheldon Adelson, a wealthy casino owner who has spent millions to boost the presidential campaign of Newt Gingrich, has donated $5 million with his wife to a super PAC for House Republican candidates, according to campaign filings released Sunday.
The Adelsons made their donations in February to the Congressional Leadership Fund, which was formed last year to be "focused solely and exclusively" on maintaining the GOP majority in the House.
The super PAC has the backing of the top GOP brass in the House. Speaker John Boehner, Majority Leader Eric Cantor and Majority Whip Kevin McCarthy were each among the 60 GOP lawmakers who attended the super PAC's inaugural event last fall.
The financial infusion immediately makes the Congressional Leadership Fund, which is chaired by former GOP Sen. Norm Coleman, among the biggest players in the congressional landscape this year.
Most of Adelson's previously reported political giving this year has gone to a super PAC devoted to electing Gingrich -- and pummeling GOP frontrunner Mitt Romney. Notably, a top Romney adviser, former Republican Rep. Vin Weber, is among the board members of the Congressional Leadership Fund PAC.
