Elon Musk made a record $158 million donation to the Senate Leadership Fund, the GOP super PAC aligned with Senate Republicans, according to CNBC. The contribution helped the group raise a total of $273 million, marking its largest fundraising haul ever.

The money is being poured into Texas, where Republicans are seeking to defend Attorney General Ken Paxton. CNBC reports that the super PAC's war chest is now being used to boost Paxton's campaign in a closely watched race.

This is the only source of reporting on the figures, and it does not provide a breakdown of other donors or spending plans. The scale of Musk's gift underscores the growing role of ultra-wealthy individuals in shaping Senate contests.
