Casino mogul Sheldon Adelson gave $5 million to YG Action Fund, a super PAC run by two former top aides to House Majority Leader Eric Cantor (R-Va.).
The donation helped YG Action Fund achieve its best fundraising quarter since opening shop last year. The super PAC raised just more than $5.3 million from April through June.
The money came just in time for the group to spend more than $500,000 to boost Richard Hudson, a former House chief of staff, in the runoff for North Carolina's 8th district on Tuesday.
This isn't the first time this year Adelson has made a multi-million dollar donation to help House Republicans. Earlier this year, Adelson and his wife donated $5 million to the Congressional Leadership Fund, a super PAC devoted to boosting Republicans in House races.
