Davidai posted that he had been cleared of allegations filed against him last year. He was previously suspended after he was accused of harassment and intimidation.

Per an email sent to Columbia Business School faculty on Wednesday morning from Dean Costis Maglaras and obtained by The Intercept, the vocal pro-Israel business school assistant professor made the decision to leave the school.

Several students, including Mahmoud Khalil and Mohsen Mahdawi, have also alleged that Davidai targeted them and called for them to be deported in the lead-up to their arrests by Immigration and Customs Enforcement.

Davidai was also a member of a prominent WhatsApp group of Columbia alumni, parents and professors that strategized about how to deport pro-Palestine students, The Intercept reported. He has noted that he does not have tenure at the school.
