Hedge fund manager Bill Ackman is wading further into the conversation about Harvard University‘s governance, backing four outsider candidates to bring “fresh blood and new perspectives” to the Board of Overseers.

Ackman, who holds a B.A. and M.B.A. from the school, threw his support behind a coalition of insurgent candidates running for the Board of Overseers under the name Renew Harvard. The billionaire is widely seen as a major force in the ouster of former Harvard President Claudine Gay.
