Kenneth C. Griffin, founder and CEO of Citadel, said he will no longer support his alma mater, Harvard University, unless it makes significant changes, Fortune reports. A Harvard College alumnus (’89), Griffin is one of the largest donors to the university, including a $300 million gift last year that renamed the Graduate School of Arts and Sciences, and $150 million in 2014. Griffin has accused elite U.S. colleges of producing “whiny snowflakes” and told members of Harvard Corporation, the university’s governing board, that he will not support the school unless it makes changes to “resume its role educating young American men and women to be leaders and problem solvers.”
