Billionaire hedge fund manager Bill Ackman is calling on Harvard University to back down in a simmering feud with President Donald Trump, arguing his alma mater is misguided and should comply with the administration’s requests.

In a lengthy post to X on Monday, Ackman said he was saddened to watch Harvard “self-immolate” over what he described as “gross mismanagement, poor governance, and ideological capture” over the last 15 years.
