Three Columbia University administrators have been “permanently removed from their positions” after sending a series of derisive text messages during a panel on campus Jewish life, Angela V. Olinto, the university’s provost, said in a statement. In an accompanying letter, Columbia President Minouche Shafik wrote that the texts echoed antisemitism and vowed to start a “vigorous program of antisemitism and antidiscrimination training” in the fall, when classes reconvene.

The three deans at the center of the group chat — Susan Chang-Kim, the university’s vice dean and chief administrative officer; Cristen Kromm, a dean of undergraduate student life, and Matthew Patashnick, an associate vice dean for student and family support — were placed on leave shortly after the texts first came to light.

Taking part in the fall training would be Josef Sorett, who was also involved in a separate text exchange with Chang-Kim during the same panel. Sorett said he had reached out to all speakers on the panel to apologize. In a petition, more than 1,000 Columbia alumni have demanded his removal. The petition said, “Sorett is wholly discredited in the eyes of alumni and students. His continuing as Dean of Columbia College is untenable.”
