Republican megadonor Timothy Mellon is withholding donations from Senate Republicans after the chamber failed to pass the SAVE America Act, according to The New York Times.

Mellon, 84, reportedly responded to a fundraising solicitation letter by saying his pockets were closed. The billionaire previously gave $30 million to the Senate Leadership Fund, the super PAC that backs Republican Senate candidates, in 2020.

Allies of Senate Majority Leader John Thune (R-SD) have tried since last year to arrange a meeting between the two men, but it never happened, according to the report.

Mellon’s decision leaves Senate Republicans without a major past benefactor as they fight to hold their majority in November, even as Mellon continues giving to other Republican groups.
