Overview
- Axios reported that during an interview at the Allen & Company Sun Valley conference, Ken Griffin said he would be predisposed to support Marco Rubio over Vice President J.D. Vance in a hypothetical 2028 Republican primary.
- Griffin is one of the party's largest individual donors and gave more than $100 million to Republican causes in 2024, making his preference potentially influential for fundraising and staffing decisions.
- The comment was made in a private forum and is reported rather than a formal endorsement, and a Griffin spokesperson declined to comment on the report.
- Marco Rubio has publicly said he would defer to Vice President Vance if Vance runs, which could limit the immediate practical effect of Griffin's private preference.
- The exchange highlights a wider GOP split between establishment figures who favor Rubio and anti‑establishment currents aligned with Vance and underscores how wealthy donors can shape early candidate viability and party dynamics.
