GOP super PAC receives major donation from casino mogul Sheldon Adelson

Young Guns Action Fund, a super PAC established to elect Republicans to the House of Representatives, received a $5 million donation from casino magnate Sheldon Adelson in April, federal disclosure records show.

The super PAC, which last week announced a partnership with a group co-founded by George P. Bush (nephew of former President George W. Bush and son of former Florida Gov. Jeb Bush) to bring more young candidates and donors into the Republican Party, also landed a $50,000 donation from the House Conservatives Fund and a $125,000 gift from hedge fund billionaire Bruce Kovner.

The latest filing makes YG Action Fund the top-fundraising super PAC focused on House races in two of the past three quarters. The group was founded in 2011 by former aides to House Majority Leader Eric Cantor.

"There's a lot of work yet to be done, but this is a serious marker which shows that the YG Action Fund is well positioned to go on offense to expand the conservative Republican majority with candidates in the Young Guns mold," said Brad Dayspring, a spokesman for YG Action.

Adelson donated millions toward Newt Gingrich's campaign during the Republican primaries and says he intends to spend $100 million this election cycle through various causes.
