Warren Buffett said he withdrew from Bill Gates’ philanthropy after concerns about ties between the Gates Foundation and convicted sex offender Jeffrey Epstein, and a new review commissioned by the foundation expanded the timeline. The external review by WilmerHale found Gates and the foundation met with Epstein more than two dozen times from 2011 to 2014, including visits to Epstein’s Manhattan home and one meeting on the foundation’s campus. The Gates Foundation said there is no evidence it paid Epstein or that it knew about ongoing sex trafficking operations, while acknowledging it regretted any employee interactions with Epstein. CEO Mark Suzman said the foundation is moving forward with Board-approved actions to strengthen partner vetting and risk management. For higher education and academic-adjacent philanthropy, the expanded disclosures reinforce compliance expectations for nonprofits that fund research and education programs—particularly when partner-risk governance becomes a public accountability issue.
