Acting Columbia President Claire Shipman announced the university will rely on a definition of antisemitism from the International Holocaust Remembrance Alliance , or IHRA. That definition has been criticized by Human Rights Watch, the ACLU, Amnesty International and an array of other groups as conflating criticism of Israel with antisemitism.

The Ivy League school adopted a controversial definition of antisemitism and will shun an anti-Israel group on campus.

Acting President Claire Shipman said the Office of Institutional Equity will use the definition to help investigate discrimination and harassment.
