A major donor to Northwestern University — who says he’s given $7 million to the institution over the years — is no longer supporting his alma mater after it canceled him.

Businessman and entrepreneur Ben Slivka wrote on his personal website that he was rejected by his beloved Northwestern — he “bled purple” for decades — after saying rude things to three students, an allegation he denies.

In his post, which was republished by Heterodox STEM, Slivka wrote he was contacted by the chief diversity officer of NU’s Athletics Department telling him several student-athletes reported they were upset with comments he made that they deemed racist or sexist. He was told to refrain from any further contact with student-athletes in any way.
