‘Don’t Say Sorry’: Columbia University Bans Pro-Israel Professor From Campus

Columbia University has “temporarily” banished its most distinguished pro-Israel Jewish professor — Shai Davidai — from campus property, a severe disciplinary sanction which prevents him from attending university functions and accessing his office.
Speaking to The Algemeiner on Wednesday morning, Davidai denounced the action as retaliation for his much publicized advocacy of Jewish civil rights, unabashed support for Zionism, and condemnations of student and faculty calls for continued acts of terrorism against Israel and other Western countries. He has, he noted, been targeted by the university before. Last semester, it launched an investigation of his conduct following spurious accusations that his denouncing terrorism amounted to anti-Muslim bigotry.
Now, the university has allegedly found cause to discipline Davidai under a microscope, punishing him for an exchange of words which took place during dueling demonstrations marking the one-year anniversary of Hamas’s Oct. 7 massacre across southern Israel. According to Davidai’s own social media account, as swarms of pro-Hamas students bellowed slogans demanding violence against Israelis, the Columbia professor filmed himself reproaching the university’s chief operating officer, Cas Holloway, for permitting anti-Israel activists to hold a celebration of the terror attack — in which Hamas-led Palestinian terrorists murdered Jewish children, sexually assaulted Jewish women and men, and kidnapped over 200 hostages during their rampage.
Footage of the encounter shows Davidai approaching Holloway and requesting that he explain the pro-Hamas demonstration’s concurrence with a Jewish-student led vigil, a circumstance that many people on campus felt was an injustice and desecration of Jewish life. Davidai then vowed to walk with Holloway until he received a sufficient response to his concerns, a not unusual behavior on Ivy League campuses, where administrative buildings have been illegally occupied and presidential offices stormed by anti-Israel demonstrators over the past year. Earlier in the day, Davidai himself was stalked by pro-Hamas activists and briefly jousted with two public safety officers about whether his freedom of movement had been violated.
“Cas, what do you have to say?” Davidai said to Holloway, with whom he crossed paths incidentally. “How could you allow this to happen on Oct. 7? … You have to do your job, and I will not let you rest until they let us rest.”
During the meeting, Davidai initiated a conversation between Holloway and an Israeli student who, like Davidai, pleaded for answers.
Holloway apologized to the student, to which Davidai responded, “Don’t say sorry if you let this happen. This is your responsibility. This is not being sorry … I’m filing a complaint with you right now, Cas. You’re the COO … You know it’s unsanctioned; you know they violated every time, place, and manner. They are hiding their faces.”
Holloway then proceeded to terminate the conversation, prompting Davidai to say, “I’m walking with you. Where are we going, Cas? Because Jewish and Israeli students don’t get to go, so where are we going? I’m walking with you. I’m not obstructing you.”
During Wednesday’s interview with the Algemeiner, Davidai defended his approach as a genuine expression of grief and concern for the welfare of Jewish students.
“People are free to see exactly the videos and see, you know, what did or did not happen and judge for themselves,” he said. “That is why I call this a clear act or retaliation. My lawyers got on a phone call with them on Oct. 7 [of this year] and were told that the university is going to suspend my ability to be on campus. On that day, the university found that the most important thing is to remove me from campus. I am, to the best of my knowledge, the only professor who has been removed from campus since Oct. 7 [2023].”
Davidai went on to point to faculty conduct which has been covered by The Algemeiner, including Columbia professor Joseph Massad publishing in Electronic Intifada an essay cheering Hamas’s atrocities as “awesome” and describing men who paraglided into a music festival to kill young people as “the air force of the Palestinian resistance.”
Davidai continued, “The only person who was removed from campus is the one that exposed the chief operating officer’s antisemitic problem. And I say this, you know, I don’t know if he is or isn’t an antisemite. I do know that he’s awfully comfortable with antisemitism and that he has an antisemitism problem.”
According to Columbia University, the campus ban, which does not affect Davidai’s compensation or employment status, was prompted by “threats of intimidation, harassment, or other threatening behavior.”
Samantha Slater, a university spokesperson, continued: “Columbia has consistently and continually respected Assistant Professor Davidai’s right to free speech and to express his views. His freedom of speech has not been limited and is not being limited now. Columbia, however, does not tolerate threats of intimidation, harassment, or other threatening behavior by its employees. Because Assistant Professor Davidai repeatedly harassed and intimidated university employees in violation of university policy, we have temporarily limited his access to campus while he undertakes appropriate training on our policies governing the behavior of our employees.”
This latest clash between Davidai and Columbia University comes during what has been widely described as an unprecedented “crisis” at the school which, since Oct. 7, 2023, has undermined its credibility with the public and drawn the scrutiny of federal lawmakers.
In April, an anti-Zionist group occupied Hamilton Hall, forcing then-university president Minouche Shafik to call on the New York City Police Department (NYPD) for help, a decision she hesitated to make and which led to over 108 arrests. However, according to documents shared in August by the US House Committee on Education and the Workforce, 18 of the 22 students slapped with disciplinary charges for their role in the incident remain in “good standing” despite the university’s earlier pledge to expel them. Another 31 of 35 who were suspended for illegally occupying the campus with a “Gaza Solidarity Encampment” remain in good standing too.
In August, Shafik resigned as president of the university, and just two months prior, in June, its legal counsel reached an out of court settlement with a student who accused administrators of neglecting their obligation to foster a safe learning environment during the final weeks of last spring semester. While stopping short of admitting guilt, the settlement virtually conceded to the plaintiff her argument that the campus was unsafe for Jewish students, agreeing to provide her and others “Safe Passage Liaisons” tasked with protecting them from racist abuse and violence.
Amid this cluster of scandals and conflagrations, Davidai has allegedly received a lion’s share of the university’s attention. Last semester, it launched an investigation of his conduct, which he called a persecution that “reveals the depths of its hostility towards its Jewish community.” He has since retained counsel to guard his rights and prevent being bulldozed by one of the wealthiest and powerful universities in the world. Despite his troubles, however, he told The Algemeiner on Wednesday that Columbia is redeemable.
“I do this because I love teaching and I love research. And because I truly believe that Columbia can become better,” he said. “For me, Cas Holloway is ruining Colombia’s reputation. He is the anathema of everything that’s right about Columbia, its educational practice, research, and openness to everyone. And I don’t know if he’s a good person or a bad person, but his inaction, his indifference shows that he’s OK with ruining everything that higher education should be standing for.”

As Gaza War Continues, Hamas Calls for Global Protests While Israel Marks Breakthroughs in Medical Innovation

As the Palestinian terrorist group Hamas calls for global protests amid stalled Gaza ceasefire talks, Israel has broken new ground despite the ongoing conflict, achieving a major medical breakthrough in synthetic human kidney development.
The contrast illustrates a stark contrast between the priorities of Hamas, an international designated terrorist group that has ruled Gaza for nearly two decades, and Israel, the lone democracy in the Middle East that has long been a leader in tech and medical innovation.
On Wednesday, Hamas urged worldwide protests in support of Palestinians, calling on the international community “to denounce Israel’s genocidal war and starvation policy in Gaza.”
“We call for continuing and escalating the popular pressure in all cities and squares on Friday, Saturday, and Sunday … through rallies, demonstrations and sit-ins outside the embassies of the Israeli regime and its allies, particularly in the US,” the statement read.
The Palestinian terrorist group also called to expose what it described as “the terrorism of the Zio-Nazi occupation against defenseless civilians.”
Hamas’s latest move against Israel comes amid stalled indirect negotiations over a proposed 60-day ceasefire and hostage release deal, which collapsed last month after the group vowed it would not disarm unless an independent Palestinian state is established — rejecting a key Israeli demand to end the war in Gaza.
In its statement, Hamas demanded the opening of all border crossings to allow immediate aid into the war-torn enclave and urged a global condemnation of “the international community’s inaction on the Israeli crimes.”
Amid mounting international pressure to address the humanitarian crisis in Gaza, Israel announced new measures to facilitate the delivery of aid, including temporary pauses in fighting in certain areas and the creation of protected routes for aid convoys.
Israeli officials have previously accused Hamas of diverting aid for terrorist activities and selling supplies at inflated prices to civilians, while also blaming the United Nations and other foreign organizations for enabling this diversion.
Hamas’s statement also emphasized that the “global resistance movement must continue until Israeli aggression on Gaza ends and the siege on the coastal strip is lifted.”
Meanwhile, as Israel faces escalating hostilities and the heavy toll of war, the Jewish state continues to push the boundaries of innovation and resilience, achieving new medical breakthroughs while confronting ongoing challenges.
In a major medical breakthrough, scientists at Sheba Medical Center and Tel Aviv University have successfully grown a synthetic 3D miniature human kidney in a lab using specialized stem cells derived from kidney tissue — one of the most promising advances in regenerative medicine.
Dr. Dror Harats, chairman of Sheba’s Research Authority, described this achievement as a reflection of Israel’s leading role in global medical innovation.
“Despite growing efforts to isolate Israel from international science, breakthroughs like this prove our impact is both lasting and essential,” he said.
In a landmark study, a team from Sheba’s Safra Children’s Hospital and Tel Aviv University’s Sagol Center for Regenerative Medicine created synthetic kidney organs that matured and remained stable for 34 weeks — the longest-lasting and most refined kidney organoids developed to date.
Nearly a decade ago, the research team became the first to successfully isolate human kidney tissue stem cells — the cells responsible for the organ’s development and growth.
Previous attempts to grow kidneys in a lab using general-purpose stem cells were short-lived, typically lasting only a few weeks and often producing unwanted cell types that compromised research accuracy.
However, this Israeli research team used stem cells taken directly from kidney tissue — cells that naturally develop into kidney parts — allowing them to create a much purer and more stable model with key features found in real kidneys.
This medical breakthrough could have far-reaching implications, redefining the current understanding of kidney diseases and advancing the development of innovative treatments.
Researchers believe the model could help assess how medications impact fetal kidneys during pregnancy and move science closer to repairing or replacing damaged kidney tissue with lab-grown cells.
The discovery came days after researchers from Hebrew University of Jerusalem and international partners discovered a way to boost the immune system’s cancer-fighting ability by reprogramming how T cells, which are white blood cells critical to the immune system, produce energy.
The researchers explained in a study published in the peer-reviewed Nature Communications that disabling a protein known as Ant2 in T cells greatly enhances their effectiveness against tumors.
“By disabling Ant2, we triggered a complete shift in how T cells produce and use energy,” Prof. Michael Berger of Hebrew University’s Faculty of Medicine, who co-led the study with doctorate student Omri Yosef, told the Tazpit Press Service. “This reprogramming made them significantly better at recognizing and killing cancer cells.”

Netherlands to Push EU to Suspend Israel Trade Deal but Won’t Recognize Palestinian State ‘At This Time’

The Netherlands is spearheading efforts to suspend the European Union-Israel trade agreement amid rising EU criticism of Israel’s actions in Gaza, while simultaneously refusing to recognize a Palestinian state, contrasting with other member states as international pressure mounts.
On Thursday, Dutch Foreign Minister Caspar Veldkamp announced that the Netherlands will push the EU to suspend the trade component of the EU-Israel Association Agreement — a pact governing the EU’s political and economic ties with the Jewish state.
This latest anti-Israel initiative follows a recent EU-commissioned report accusing Israel of committing “indiscriminate attacks … starvation … torture … [and] apartheid” against Palestinians in Gaza during its military campaign against Hamas, an internationally designated terrorist group.
Following calls from a majority of EU member states for a formal investigation, this report built on Belgium’s recent decision to review Israel’s compliance with the trade agreement, a process initiated by the Netherlands and led by EU High Representative for Foreign Affairs and Security Policy Kaja Kallas.
According to the report, “there are indications that Israel would be in breach of its human rights obligations” under the 25-year-old EU-Israel Association Agreement.
While the document acknowledges the reality of violence by Hamas, it states that this issue lies outside its scope — failing to address the Palestinian terrorist group’s role in sparking the current war with its bloody rampage across southern Israel on Oct. 7, 2023.
Israeli officials have slammed the report as factually incorrect and morally flawed, noting that Hamas embeds its military infrastructure within civilian targets and Israel’s army takes extensive precautions to try and avoid civilian casualties.
In a Dutch parliamentary debate on Gaza on Thursday, Veldkamp also announced that the government would not recognize a Palestinian state for now — a position that stands in sharp contrast to the recent moves by several other EU member states to extend recognition.
“The Netherlands is not planning to recognize a Palestinian state at this time,” the Dutch diplomat said.
“This war has ceased to be a just war and is now leading to the erosion of Israel’s own security and identity,” he continued.
This latest decision goes against the position of several EU member states, including France, which has committed to recognizing Palestinian statehood in September.
The United Kingdom has likewise indicated it will do so unless Israel acts to ease the humanitarian crisis in Gaza and agrees to a ceasefire.
For its part, Germany said it was not planning to recognize a Palestinian state in the short term, and Italy argued that recognition must occur simultaneously with the recognition of Israel by the new entity.
Spain, Norway, Ireland, and Slovenia all recognized a Palestinian state last year.
Israel has been facing growing pressure from several EU member states seeking to undermine its defensive campaign against the Palestinian terrorist group Hamas in Gaza.
On Thursday, European Commission Vice President Teresa Ribera strongly condemned Israel’s actions in the war-torn enclave, describing the situation as a “grave violation of human dignity.”
“What we are seeing is a concrete population being targeted, killed and condemned to starve to death,” Ribera told Politico. “If it is not genocide, it looks very much like the definition used to express its meaning.”
Until now, the European Commission has refrained from accusing Israel of genocide, but Ribera’s comments mark one of the strongest European condemnations since the outbreak of the war in Gaza.
She also called on the EU to take decisive action by considering the suspension of its trade agreement with Israel and the implementation of sanctions, while emphasizing that such measures would require unanimous approval from all member states.

Graduate Student Unions Promoting Antisemitism, Reform Group Says

Higher-education-based unions controlled by United Electrical, Radio, and Machine Workers of America (UE) are rife with antisemitism and anti-Zionist discrimination, according to a new letter imploring the US Congress’s House Committee on Education and the Workforce to address the matter.
“Tracing its roots to communism in the 1930s, the UE is a radical, pro-Hamas labor union that has a long history of antisemitism,” the National Right to Work Foundation (NRTW), one of the US’s leading labor reform groups, wrote on July 30 in a message obtained by The Algemeiner. “The UE openly supports the boycott, divestment, and sanctions (BDS) movement, which is designed to cripple and destroy Israel economically. Today, the UE furthers its antisemitic agenda by unionizing graduate students on college campuses and using its exclusive representation powers to create a hostile environment for Jewish students. The hostile environment includes demanding compulsory dues to fund the UE’s abhorrent activities.”
NRTW went on to describe a litany of alleged injustices to which UE members subject Jewish student-employees in the US’s most prestigious institutions of higher education, from the Massachusetts Institute of Technology (MIT) to Cornell University. At MIT, the letter said, “union officers” aided a riotous group which illegally occupied a section of campus with a “Gaza Solidarity Encampment,” participating in the demonstration and even denying access to campus buildings. UE members at Stanford University, meanwhile, allegedly denied religious accommodations to Jewish students who requested exemption from union dues over that branch’s supporting the BDS movement. And Cornell University UE was accused of denying religious exemptions in several cases as well and followed up the rejection with an intrusive “questionnaire” which probed Jewish students for “legally-irrelevant information.”
The situation requires federal oversight and intervention, NRTW said, including Congress’s possibly clarifying that student-employees are not traditional employees and are therefore afforded protections under sections of the Civil Rights Act which apply to the campus.
“These continuing patterns of antisemitism are illegal, immoral, and must be stopped,” the letter continued. “We encourage you to do all that is in your power to investigate and help bring an end to the UE and its affiliates’ nonstop harassment and intimidation of Jewish students … The Trump administration can also use tools available to it under Title VI and Title VI of the Civil Rights Act against colleges who work with unions to create a hostile environment for Jewish students.”
July’s letter is not the first time NRTW has publicized alleged antisemitic abuse in unions representing higher education employees.
In 2024, it represented a group of six City University of New York (CUNY) professors, five of whom are Jewish, who sued to be “freed” from CUNY’s Professional Staff Congress (PSC-CUNY) over its passing a resolution during Israel’s May 2021 war with Hamas which declared solidarity with Palestinians and accused the Jewish state of ethnic cleansing, apartheid, and crimes against humanity. The group contested New York State’s “Taylor Law,” which it said chained the professors to the union’s “bargaining unit” and denied their right to freedom of speech and association by forcing them to be represented in negotiations by an organization they claim holds antisemitic views.
That same year, NRTW prevailed in a discrimination suit filed to exempt another cohort of Jewish MIT students from paying dues to the Graduate Student Union (GSU). The students had attempted to resist financially supporting GSU’s anti-Zionism, but the union bosses attempted to coerce their compliance, telling them that “no principles, teachings, or tenets of Judaism prohibit membership in or the payment of dues or fees” to the union.
“All Americans should have a right to protect their money from going to union bosses they don’t support, whether those objections are based on religion, politics, or any other reason,” NRTW said at the time.
