Last week’s assassination of conservative activist Charlie Kirk has animated a wave of anti-Israel conspiracy theories, inspiring voices on both the far right and far left to join together in promoting an assortment of unsubstantiated claims inflected with conventional antisemitic tropes.

On Monday, Kirk’s producer and a billionaire supporter of Israel both rejected the allegations fueled by Max Blumenthal, a fiercely anti-Israel journalist promoted by Iranian state media who carries a long record of smearing the Jewish state.

Blumenthal, editor of the Grayzone website, published claims from anonymous sources that Kirk had been pressured at a Hamptons gathering hosted by billionaire Bill Ackman weeks before his death. Kirk was reportedly “hammered” over his views on Israel by Ackman and other pro-Israel advocates, leaving him to feel blackmailed.

The report named Natasha Hausdorff of UK Lawyers for Israel as among those who berated Kirk. Hausdorff confirmed to the New York Post that she attended the meeting but called the accusation “categorically untrue” and added that whoever said it “is absolutely lying.” Ackman also denied the charge, calling the claim “totally false.”

Blumenthal has long written articles sympathetic to Hezbollah, the former Assad regime in Syria, and Hamas. In 2013, he notably published Goliath: Life and Loathing in Greater Israel, which Eric Alterman, media columnist for the leftist flagship magazine The Nation, described as “a propaganda tract” that could “have been published by the Hamas Book-of-the-Month Club (if it existed).”

The Grayzone report has since influenced Candace Owens, the podcaster who has been widely accused of antisemitism, and US Rep. Marjorie Taylor Greene (R-GA), among others, demonstrating a convergence between far-left and far-right figures in promoting antisemitic narratives and anti-Israel conspiracies.

Owens — who previously worked with Kirk before her shift to open, unapologetic opposition to Israel and promotion of antisemitic conspiracy theories, which resulted in her termination from her job as podcaster at The Daily Wire in March 2024 — claimed during a Monday monologue that pro-Israel forces staged an “intervention” with Kirk involving Ackman and Israeli Prime Minister Benjamin Netanyahu. She alleged Kirk, an outspoken supporter of Israel who often called out the dangers of antisemitism, was changing his views and offered “a ton of money” to remain pro-Israel, comparing the meeting to a “re-education camp.” Owens said Kirk refused the offers, warning her followers to be “very wary and suspicious of the people who are already telling us to stop asking questions about the Charlie Kirk assassination.”

The podcaster later clarified that she was not directly accusing Israel of orchestrating the murder but argued Kirk had faced “extreme pressure” over his views. Owens also shared social media posts criticizing Netanyahu, captioning one with “All will be revealed.”

Ackman, founder of Pershing Square Capital Management, responded on X, saying Owens had “slandered” him by accusing him of staging an intervention and suggesting that he blackmailed Kirk. He denied ever offering Kirk or Turning Point USA, the political advocacy organization he started, any money, pressuring him on Israel, or threatening him. “In short, this was not an ‘intervention’ to ‘blackmail’ Charlie Kirk into adopting certain views on Israel,” Ackman wrote in his statement. He described his interactions with Kirk as cordial and said he admired him.

Ackman said he and Kirk first connected on Zoom in June, then worked together to organize a conference of conservative influencers in Bridgehampton in August. He said about 35 influencers attended, collectively reaching more than 100 million followers, and that discussions included a range of issues such as economics, dating, immigration, and Israel. He added that participants expressed varied views on Israel and US support for the country.

Andrew Kolvet, executive producer of “The Charlie Kirk Show,” corroborated Ackman’s account. In a statement, Kolvet said he had spoken with three Turning Point staffers who were present at the gathering in question and that “Bill never yelled at Charlie, never pressed him on Bibi [Netanyahu], never gave him a list of Charlie’s offenses against Israel.” Kolvet added that Kirk himself had told him he had a “cordial relationship” with Ackman and that the event was “productive.”

Despite those denials, the conspiracy theories gained further traction on the far right. Greene wrote on X that supporters should “believe Candace Owens and Tucker Carlson” over “Bibi Netanyahu (a foreign country’s leader),” before warning: “Do not allow a foreign country, foreign agents, and another religion tell you about Charlie Kirk. And I hope a foreign country and foreign agents and another religion does not take over Christian Patriotic Turning Point USA.” She described Kirk as a “Christian martyr” and suggested Jewish influence threatened his movement.

On July 28, Greene accused Israel of engaging in a genocide in Gaza.

The New York Post reported that Owens’ comments relied in part on Blumenthal’s Grayzone article. In addition, Owens suggested law enforcement had intentionally allowed Kirk’s killer to evade capture, though police have charged 22-year-old Tyler Robinson of Utah with the shooting.

Authorities have not presented any evidence linking Israel or pro-Israel figures to the crime. Rather, the alleged shooter’s animosity toward Kirk’s positions on LGBTQ issues appears to have inspired the attack, according to prosecutors.

Violence and intimidation against Jewish and Israeli students as well as faculty are on the rise across European campuses, as an Italian professor was assaulted at the University of Pisa and students in France were excluded from online groups over their Jewish identities.

On Tuesday, pro-Palestinian protesters stormed a classroom at the University of Pisa in Tuscany, Italy, and assaulted an Italian professor who has opposed cutting ties with Israeli universities.

According to local reports, protesters burst into the classroom waving Palestinian flags and shouting antisemitic slurs, targeting the professor over his opposition to the university’s recent decision to sever ties with two Israeli universities.

A student who tried to intervene was attacked by protesters. When the professor stepped in to protect him, he too was assaulted and later hospitalized with injuries to his head and arms.

On the same day, anti-Israel protesters disrupted a lecture by a visiting Israeli speaker at the Polytechnic University of Turin in northern Italy, shouting antisemitic slogans as they stormed the classroom.

Shortly after the incident, the university announced it was cutting ties with the speaker because he had defended the Israel Defense Forces (IDF) during the confrontation with the protesters.

Since the Hamas-led invasion of and massacre across southern Israel on Oct. 7, 2023, anti-Israel activity on campuses has intensified, with Jewish and Israeli students facing frequent targeting and isolation in an increasingly hostile environment.

On Monday, a group of first-year economics students at Panthéon-Sorbonne University in Paris created a group chat on Instagram that excluded several students, accusing them of being Zionists based on their Jewish-sounding names or surnames, French media reported.

“If there are any other Zionists in this group besides those I’ve already kicked out, leave now — we don’t want you here,” wrote one of the students who created the group, placing a Palestinian flag in the middle.

This latest antisemitic incident follows a similar episode last month, when a student created a poll in a WhatsApp group chat titled, “For or Against Jews?”

Yossef Murciano, president of the Union of Jewish Students of France (UEJF), denounced the rising wave of anti-Jewish incidents, noting that the group had posted notices across multiple campuses to highlight the latest antisemitic episodes.

“We reported the incident to the university, but so far nothing has been done. We were told that measures would be taken, but we don’t know when or how,” Murciano said.

In a press release, the university strongly condemned such “unacceptable behavior,” expressing its full support for those students affected by the recent antisemitic incidents.

The university also announced that it had submitted “all available evidence to the public prosecutor” regarding these two incidents and plans to initiate “disciplinary proceedings” against each of the perpetrators.

“These two acts, whose antisemitic nature seems clear, deserve a punishment commensurate with their severity,” the statement read.

French Minister of Higher Education and Research Philippe Baptiste strongly condemned the latest incidents, demanding a zero-tolerance approach.

“I stand with these young people, victims of antisemitism that must be opposed everywhere, including, sadly, in our universities. There is only one possible response: zero tolerance!” Baptiste wrote in a post on X.

A l’université Paris 1, des étudiants juifs exclus d’un groupe Whatsapp d’élèves sur la base de leurs noms ! J’apporte tout mon soutien à ces jeunes, victimes de l’antisémitisme que nous devons combattre partout, y compris, malheureusement, dans nos universités. Une seule ligne…

Yonathan Arfi, president of the Representative Council of Jewish Institutions in France (CRIF), also spoke out against the incident, calling it a disturbing example of rising antisemitism on campuses.

“This is not a pro-Palestinian campaign, it is a campaign of antisemitic intimidation,” Arfi said in a post on X.

“Si d’autres sionistes comme ceux que j’ai déjà retirés sont présents, vous pouvez quitter. On ne veut pas de vous ici ”

The incidents occurred weeks after two international Jewish groups and a German watchdog published a report showing that antisemitism on European university campuses following Hamas’s Oct. 7 invasion of Israel has fostered a “climate of fear” for Jewish students.

Then earlier this week, the Anti-Defamation League (ADL) and the World Union of Jewish Students (WUJS) released their own report which found that the vast majority of Jewish students around the world resort to hiding their Jewishness and support for Israel on campuses to avoid becoming victims of antisemitism.

A journalist at Canada’s national public broadcaster, Radio-Canada, has been suspended after using antisemitic language during a Monday television broadcast, prompting an official apology from the network.

On the news program “Sur le terrain,” correspondent Élisa Serret, reporting from Washington on US Secretary of State Marco Rubio’s visit to Israel, was asked why the US continues to support Jerusalem despite its recent military offensive in Gaza.

Serret responded, saying in French, “The Israelis, in fact the Jews, finance a lot of American politics” and control a “big machine.”

The journalist then went on to claim that the largest US cities and Hollywood are “run by Jews,” echoing long-standing antisemitic stereotypes and hateful rhetoric about supposedly outsized and nefarious Jewish power.

After Serret’s comments went viral, sparking outrage from political leaders and the local Jewish community, Radio-Canada issued an apology, describing her remarks as “”stereotypical, antisemitic, erroneous, and prejudicial allegations against Jewish communities.”

“These unacceptable comments violate Radio-Canada’s Journalistic Standards and Practices and do not reflect the views of the public broadcaster,” the statement read.

“As a result, the news department has decided to relieve the journalist of her duties until further notice,” it continued. “We are aware that these comments have offended many viewers. We sincerely apologize and regret this.”

The Center for Israel and Jewish Affairs (CIJA), a Canadian Jewish advocacy group, strongly condemned Serret’s comments, accusing Radio-Canada of spreading “antisemitic lies.”

Eta Yudin, CIJA’s vice-president for Quebec, called on the public broadcaster to take concrete measures to keep antisemitic content out of Canadian homes.

“This incident cannot be allowed to pass without serious internal reflection on the damage such hateful rhetoric inflicts on our democratic values,” Yudin said in a statement. “Antisemitism is corroding the fabric of our society.”

Canadian Identity and Culture Minister Steven Guilbeault, who is responsible for overseeing the public broadcaster, also condemned the incident, saying that “antisemitism has no place in Canada” and describing Serret’s remarks as “pernicious antisemitic tropes.”

“When antisemitic language is used by journalists, or anyone in a position of trust, it risks normalizing hatred in deeply dangerous ways,” Guilbeault said.

Anthony Housefather, the government’s special adviser on Jewish community relations and antisemitism, denounced the incident, saying Serret’s remarks echoed “textbook tropes that are antisemitic under the IHRA definition,” referring to the International Holocaust Remembrance Alliance (IHRA) definition of antisemitism, which was adopted by the government in 2020.

Melissa Lantsman, a member of the opposition Conservative Party, criticized the public broadcaster for failing to “uphold the values of this country” by airing what she described as an “antisemitic rant.”

“Overt antisemitism on TV is part of the deep systemic rot corroding our society, and it flourishes when tax-funded institutions provide it with a platform,” Lantsman said in a statement.

“Canadians deserve better than excuses and carefully worded apologies,” she continued.
