Columbia University prepares for more anti-Israel protests on the eve of Passover, with a Jewish professor asking to march through campus to the protest with a police escort, and a rabbi warning his fellow Jews to stay off campus remain until the protests subside.

On Monday, a professor at Columbia Business School, Shai Davidai, said he plans to walk onto campus and sit among anti-Israel protesters. He asks the university leadership to provide him with a police escort because he has spoken out online about the anti-Semitic protests and Israel’s right to defend itself.

“I am on campus on Monday morning and am asking for (a) police escort,” said Mr. Davidai on X. “Police escort to simply go to my own workplace.”

“Last time I checked, I’m still a professor at Columbia University,” he wrote in a letter to the university’s leadership, which he shared online. “I plan to go tomorrow, Monday morning, and sit peacefully in the middle of the illegal encampment that you allowed the pro-Hamas mob to establish in the middle of campus.”

“I will be joined by several Jewish and Israeli students, faculty and staff. I request permission to have a police escort of at least ten officers with me. … We come. I’m an employee and they are your students. You have a responsibility to protect our physical safety,” he wrote.

Mr. Davidai wrote the email Sunday morning, just hours after a raucous Saturday evening on the Ivy League campus. In a video posted online, pro-Israel students peacefully chant with American and Israeli flags. Directly in front of them is a person whose face is hidden by a keffiyeh, holding a sign that reads ‘Al-Qassam’s next target’, with an arrow pointing to the flag holders. The Al-Qassam Brigades are the military wing of Hamas.

Other videos Posted online, the protesters showed themselves calling for violence against Jews and Israel, chanting: “We say justice, you say how? Burn down Tel Aviv”, “Al-Qassam, you make us proud, take out another soldier” and “Hamas, we love you. We also support your missiles.”

The encampment on Columbia’s main campus lasted days. Congresswoman Ilhan Omar’s daughter was suspended from Barnard College for her involvement in the protest and her refusal to leave the area. Ultimately, New York City police were called in to disperse the camp, although students continue to protest on the green.

Things have gotten so bad on campus for Jewish students that one rabbi is calling on his fellow Jews to leave Columbia until the protests subside. In a message shared with CNN’s Jake Tapper, Rabbi Elie Buechler “strongly” urged Jewish students to take a break from school.

“What we see on and around campus is terrible and tragic. The events of the past few days, especially last night, have made it clear that Columbia University Public Safety and the NYPD cannot guarantee the safety of Jewish students in light of

extreme anti-Semitism and anarchy,” Rabbi Buechler writes to his students.

“It pains me to say that I would strongly advise you to return home as soon as possible and to stay at home until the reality on and around campus has improved dramatically,” he continued. He ends his message, sent Sunday, by saying, “It is not our job as Jews to ensure our own safety on campus. No one should have to put up with this level of hate, let alone at school.”

A prominent New York financier who has been active in efforts to suppress anti-Semitism at Harvard and other universities, Bill Ackman, was among those who criticize the apparent double standard exhibited by the university. “How would Columbia respond if students took over campus in support of the KKK and called for the genocide of other ethnic minorities?” he said in an online post. “Would Columbia continue to support the demonstrations based on a commitment to freedom of expression or would the university’s code of conduct suddenly have an operational impact?”

In a rack Released Sunday, a New York Republican Party congresswoman, Elise Stefanik, said it was time for the university’s president, Nemat “Minouche” Shafik, to consider resigning. “Over the past few months and especially over the past 24 hours, Columbia’s leadership has clearly lost control of the campus, putting the safety of Jewish students at risk,” she said. “It is crystal clear that Columbia University – previously a beacon of academic excellence founded by Alexander Hamilton – needs new leadership.”

On Sunday afternoon, students were still camping on Columbia’s main lawn.
