Asked by media figure Andrew Ross Sorkin on Wednesday whether he would back Secretary of State Marco Rubio or Vice President JD Vance in a 2028 Republican presidential primary contest, multibillionaire Ken Griffin indicated that he had backed Rubio in the past and would be predisposed to do so again, Axios reported.
The exchange occurred during an interview at the Allen & Company conference in Sun Valley, Idaho, according to the outlet, which noted that Griffin did not state what he would do to assist Rubio.
Axios reporter Alex Isenstadt noted in the article that in his 2025 book, “Revenge: The Inside Story of Trump’s Return to Power,” he reported that Griffin urged then-former President Donald Trump not to pick Vance as his 2024 running mate.

Rubio has indicated that he will not challenge Vance if the vice president throws his hat into the ring for the upcoming presidential race.
