Tensions ran high Sunday afternoon at Brooklyn’s Congregation Beth Elohim, where dozens of pro-Israel protesters gathered to oppose mayoral frontrunner Zohran Mamdani’s appearance at the synagogue.
Mamdani’s visit, his first speaking engagement at a Jewish institution since before the primary election, was billed to the Reform synagogue’s congregants as an opportunity to hear directly from the candidate that has drawn condemnation from some Jewish New Yorkers for his sharp stances against Israel.
Mamdani has faced backlash from Jewish leaders for his failure to condemn the pro-Palestinian phrase “globalize the intifada,” as well as for his support for the Boycott, Divest and Sanctions movement against Israel. He has since said he would “discourage” use of the slogan and has sought to strengthen relations with Jews in New York.
Some congregants at Congregation Beth Elohim, or CBE, objected to Mamdani’s visit, which directly followed his participation in the NYC Gaza 5K raising money for the Palestinian aid agency UNRWA, held in nearby Prospect Park on Sunday morning.
Elaine Kleinberg, a 25-year member of CBE, joined the ranks of the roughly three dozen protesters gathered across the street of the event out of fear that her temple was being used as a “political prop.”
“I think it’s very clear that any group that wants Israel to be eliminated is not to be embraced by our congregation. It’s like inviting Yasser Arafat into our midst,” said Kleinberg. “I feel very tormented right now and conflicted because I felt like this was my welcoming sanctuary, and I’m not so sure.”
A Park Slope pro-Israel activist, Ramon Maislen, helped organize the event. “Does anyone think that CBE would invite a Proud Boy adjacent Republican candidate for Mayor who said that White Power meant different things to different people just 3 weeks before the election?” he tweeted late Sunday, reiterating his comments from the demonstration.
The demonstrators waved Israeli flags and held signs reading “No to Zoh-cialism,” “Jews for Jihadists?” and “Make Love not Intifada.” As the crowd grew, a passing driver yelled “Free Palestine,” prompting one protester to shout back at him.
While the protesters seemed to be mixed between congregants and those unaffiliated with CBE, as the demonstration began singing “Shalom Aleichem,” a song of peace, congregants in line across the street joined the chorus.
Rabbi Rachel Timoner, the senior rabbi of CBE, said she felt that the protesters misunderstood the purpose of Mamdani’s visit.
“I feel that there’s a misunderstanding with the people outside, because I think that they clearly are viewing this as if it’s an act of support, and it is actually an act of expressing the views of the Jewish people as they affect our city,” said Timoner, who spoke last week at an Oct. 7 vigil held by Israelis for Peace that Mamdani attended.
Last month, CBE hosted a member listening circle that centered on congregants’ thoughts about the mayoral race. There, Timoner said many expressed a desire to ask questions to the candidates directly.
In response to that sentiment, Timoner said CBE had invited all the mayoral candidates to speak and take questions from congregants. Mamdani’s appearance, she noted, would be followed by a discussion with Curtis Sliwa next week. (She added that Cuomo’s campaign had not responded to multiple invitations.)

For Mamdani’s appearance Sunday, Timoner said they had received almost 400 registrations and 82 member-submitted questions to pose to the mayoral frontrunner. Of the questions selected to be asked of Mamdani, she said about half related to his stances on Zionism, Israel and antisemitism while the rest focused on his policies.
Timoner said she received between 15 and 20 emails from congregants urging her to cancel the event, fearing it could be seen as an endorsement.
“This is not in any way about endorsing a candidate,” said Timoner. “This is about platforming our members’ concerns, lifting up our members’ concerns in the conversation about the future of our city.”
Among the synagogue’s most prominent members is Sen. Chuck Schumer, the Senate minority leader who has not endorsed Mamdani despite criticism from others in the Democratic Party.
To quell concerns that the visit could be seen as a “photo-op” for the candidates, Timoner said Mamdani and Sliwa had both agreed not to post about the events on social media.
Speaking with the Jewish Telegraphic Agency ahead of the event, which was closed to the press, Timoner said she hoped the engagement could offer Mamdani an opportunity to hear from Jewish New Yorkers directly.
“I am hoping that he is going to hear us. We’re going to ask some hard questions, and we’re going to raise some deep concerns, and I’m hoping that he is going to listen with an open mind and an open heart to the real pain and fear and experience of the Jewish community,” said Timoner.
Following the event, as roughly 300 congregants filed out of the synagogue, reactions to his appearance were mixed.
“I walked in on the fence, not feeling comfortable voting for Cuomo, although I voted for him in the primary, and definitely not going to vote for Sliwa,” said one 80-year-old congregant who requested anonymity to protect his privacy as a voter. “I left a little more leaning towards Mamdani. I really want to like him. He’s a likable guy. I think he provides some sense of enthusiasm for big portions of our population.”
When asked how he felt about Mamdani’s responses to questions about his stances on anti-Zionism and antisemitism, the congregant said he was “trying to figure out how to deal with that.”
“The guy has a history of being pro-Palestinian and anti-Zionist, anti-Israel as a Jewish state. I am typical of this community, anti-the prosecution of the war by the current Israeli government. I’m against them, but I am for Israel as a Jewish state, and I’m not quite sure. He’s still sort of vague where he stands or not,” the congregant said.
He described Mamdani’s responses to questions about Israel as including “a lot of nice rhetoric,” but said he was unsure how things would play out if he is elected.
“I’m not sure what happens if there are anti-Jewish protesters, protests or actions against Jewish students,” the congregant said. “I don’t know what he’d do about that. Would he come down hard? Does he lean a certain way?”
