Three Columbia University deans have been “permanently removed” from their posts for sharing “very troubling” texts that “disturbingly touched on ancient antisemitic tropes,” school officials said Monday.

The three administrators — Susan Chang-Kim, Matthew Patashnick and Cristen Kromm — have been on leave since last month since it emerged they’d been involved in the disparaging text exchange that unfolded during a panel discussion about antisemitism on campus.

“This incident revealed behavior and sentiments that were not only unprofessional, but also, disturbingly touched on ancient antisemitic tropes,” Columbia president Minouche Shafik said in a statement.

“Whether intended as such or not, these sentiments are unacceptable and deeply upsetting, conveying a lack of seriousness about the concerns and the experiences of members of our Jewish community that is antithetical to our university’s values and the standards we must uphold in our community.”
