Outspoken Jewish professor barred from Columbia campus — but administration turns blind eye to even bigger tent city springing up

A Columbia University professor who has been a vocal critic of the administration’s response to the ongoing anti-Israel student protests was barred from campus Monday after he tried to lead a pro-Jewish rally at the Ivy League college.

Israel-born Shai Davidai, an assistant professor at Columbia Business School and an outspoken supporter of the Jewish state, was told that his ID had been “deactivated” — even as a massive new tent city sprang up on the Morningside Heights campus with some 200 protesters — all of whom would have had to use their Columbia IDs to get in. 

He said administrators told him they banned him from campus because they could not ensure his safety.
