Conservative mega-donors Sheldon and Miriam Adelson funneled nearly $35 million into Republican coffers in recent months, making them a primary source of strength for the GOP as it fights to maintain control of the House and Senate going into the midterm campaign‘s final stretch.

The Adelsons have spent more than $90 million on GOP causes so far this cycle, according to Federal Election Commission filings, and their third-quarter giving cemented their status as the Republican Party’s biggest donors.


Sheldon Adelson, a backer of President Donald Trump, is CEO and chairman of Las Vegas Sands, a global casino empire. In September, he and his wife each gave $10 million to the Congressional Leadership Fund, a super PAC linked to House Speaker Paul Ryan, a new FEC filing Monday showed. It was the couple’s second major infusion of cash to help save the Republican House majority and accounted for nearly 80 percent of the fund’s haul of about $25.5 million last quarter.

That was on top of $55 million the pair had already given the Congressional Leadership Fund and another super PAC focused on helping Republicans keep control of the Senate. They have also given smaller amounts to individual GOP candidates.

The Adelsons also gave a combined $10 million to America First Action, a super PAC that supports Trump's agenda, contributing the lion's share of the $12 million the group brought in during the third quarter. In recent weeks, the PAC has funded negative television ads targeting Democratic Sen. Jon Tester of Montana, who is in a tough re-election fight.

In September, the Adelsons also gave $2 million to ESAFund, which supports small-government candidates. Last quarter, the fund spent $1 million to oppose Democratic Rep. Beto O’Rourke, who is challenging Republican Sen. Ted Cruz in Texas.

All three political action committees are super PACs, meaning they have no limit on donations or spending.

In addition, the couple gave nearly $3 million to the Republican Governors Association in July and September, the filings showed.
