Zohran Mamdani, the Democratic nominee for mayor of New York City, expressed disagreement on Thursday with comments by Hasan Piker, a far-left streamer who has said “America deserved 9/11,” after several months in which the state assembly member had declined to condemn such rhetoric.

“I find the comments that Hasan made on 9/11 to be objectionable and reprehensible,” Mamdani said during the first general election debate on Thursday night, where he traded barbs with former New York Gov. Andrew Cuomo, who is trailing in the polls as he mounts an independent run following his primary loss to Mamdani in June.

Still, Mamdani, a 33-year-old democratic socialist, defended his decision to appear on Piker’s show for an extensive interview during the primary — even as the streamer has otherwise frequently stirred controversy for using antisemitic rhetoric in his commentary on Israel and Jewish issues. 

“I also think that part of the reason why Democrats are in the situation that we are in, of being a permanent minority in this country, is we are looking only to speak to journalists and streamers and Americans with whom we agree on every single thing that they say,” Mamdani argued, while making no mention of Piker’s antisemitic comments. “We need to take the case to every person, and I am happy to do that.”

Piker has faced criticism for justifying Hamas’ Oct. 7, 2023, attacks and forcefully denying some of the terror group’s atrocities — including widespread reports of sexual violence. In one notable stream last year, Piker said “it doesn’t matter if rapes f***ing happened on Oct. 7,” while adding that “the Palestinian resistance is not perfect.” He has also described Orthodox Jews as “inbred” and compared Zionists to Nazis, among other slurs seen as antisemitic.

Elsewhere during the debate, Mamdani, an outspoken critic of Israel who was arrested in October 2023 during a ceasefire demonstration outside the Brooklyn home of then-Senate Majority Leader Chuck Schumer (D-NY), declined to confirm that he would not participate in protests if he is elected mayor. “The important thing is to lead from City Hall,” Mamdani said. “That’s what I’ll be doing.”

Mamdani had faced intense backlash before the debate for comments during a Fox News interview released on Wednesday in which he avoided directly answering a question about whether Hamas should disarm and relinquish its leadership role in Gaza. He clarified at the debate that Hamas, as well as “all parties,” “should lay down” their arms but did not comment on its future role in the conflict.  

“I’m proud to be one of the first elected officials in the state who called for a ceasefire, and calling for a ceasefire means ceasing fire,” Mamdani said. “That means all parties have to cease fire and put down their weapons. And the reason that we call for that is not only for the end of the genocide, but also an unimpeded access of humanitarian aid.”

He added that “we also have to ensure that [the ceasefire] addresses the conditions that preceded this, conditions like occupation, like the siege and apartheid, and that is what I’m hopeful for.”

Mamdani, who has seen mixed results in his continued outreach to the Jewish community, also once again refused to condemn the phrase “globalize the intifada” — even as he reiterated that it “evokes many painful memories” for Jewish voters and reiterated he will “discourage” its usage.

Zohran Mamdani, the Democratic nominee for mayor of New York City, attended his first Rosh Hashanah service on Monday night at a Brooklyn synagogue well-known for its anti-Zionist activism.

The visit to Kolot Chayeinu, a nondenominational synagogue in Park Slope that has drawn controversy over its anti-Zionist orientation, comes as Mamdani is seeking to engage in increased outreach to Jewish voters ahead of the November election.

But the venue choice also underscores his polarizing position in the broader Jewish community — where many Jewish leaders have continued to raise alarms over his anti-Israel policies and refusal to condemn calls to “globalize the intifada,” among other issues.

Mamdani, an outspoken critic of Israel who has identified as anti-Zionist, was warmly received at the Monday service, where he sat in the front row in a mask and a yarmulke beside Brad Lander, the city comptroller who is a member of Kolot Chayeinu.

Lander, a close ally of Mamdani, recently described the congregation, which was one of the first to call for an early ceasefire in October 2023, as a meeting point for anti-Zionist Jews and progressive Zionists like himself.

The synagogue, which maintains an “open tent” policy on Israel and Palestine, has faced criticism for promoting anti-Israel views in its Hebrew school curriculum in the aftermath of Hamas’ Oct. 7, 2023, attacks. 

In one particularly controversial  lesson, students were instructed to write a letter of apology rebuking their Jewish “ancestors” for taking Palestinian land, fueling concerns among parents who objected to the politicized assignment.

A rabbi at Kolot Chayeinu, Abby Stein, who is a member of the anti-Zionist group Jewish Voice for Peace, also drew scrutiny for attending a meeting in New York City last year with Iranian President Masoud Pezeshkian, days before the Islamic Republic launched a missile attack against Israel.

Mamdani, a 33-year-old democratic socialist and assemblyman from Queens, did not deliver remarks at the Monday evening service. During his sermon, the rabbi accused Israel of committing genocide in Gaza, a claim that Mamdani has frequently made.

Mamdani is now expected to appear at other Jewish institutions during the High Holidays, including a mainstream congregation on Manhattan’s Upper West Side — where he could face a less welcoming audience skeptical of his hostile views toward Israel.

A spokesperson for Mamdani did not respond to a request for comment about his planned outreach to the Jewish community.

Jay Jacobs, the chairman of the New York Democratic Party, said on Thursday he will not endorse Zohran Mamdani for mayor of New York City, notably breaking with Gov. Kathy Hochul, who recently announced her support for the Democratic nominee.

In a statement, Jacobs said he had a “positive conversation” with Mamdani, the 33-year-old democratic socialist and Queens assemblyman, soon after the primary, and dismissed what he called “the fear-mongering around him and his candidacy” as “wrong and a gross over-reaction.”

But while Jacobs said he shared Mamdani’s belief that “America’s greatest problem is the continued growth in income disparity in our nation,” the state party chair noted they “fundamentally disagree” on “how to address it.” 

Jacobs, who is Jewish, also cited Mamdani’s staunch opposition to Israel, an issue on which the nominee has recently indicated he has no intention of budging, as a major source of contention.

“Furthermore, as I expressed to him directly, I strongly disagree with his views on the State of Israel, along with certain key policy positions,” Jacobs said of Mamdani, who has vowed to arrest Israeli Prime Minister Benjamin Netanyahu if he is elected and said he would move to terminate a city program to foster partnerships between companies in Israel and New York City, among other positions that have raised concerns among Jewish leaders.

Jacobs did not elaborate on particular policies that Mamdani has proposed, including free bus service, government-run grocery stores, universal childcare and rent freezes, some of which have faced scrutiny from the business and real estate communities.  

He also voiced strong objections to the far-left platform of the Democratic Socialists of America, of which Mamdani has long been a member, saying he did not believe the group “represents the principles, values or policies of the Democratic Party.”

“For those reasons I will not be endorsing Mr. Mamdani for mayor of New York City,” Jacob said in his statement. 

The decision to withhold his support for Mamdani comes as the mayoral nominee has claimed backing from a growing number of mainstream Democratic leaders in New York, most recently Carl Heastie, the speaker of the state Assembly, a prominent holdout who issued his endorsement on Wednesday — days after Hochul made her announcement last weekend. 

Still, some of the state’s top Democratic elected officials, including Senate Minority Leader Chuck Schumer (D-NY) as well as House Minority Leader Hakeem Jeffries (D-NY), have continued to remain on the sidelines, with less than two months until the November election.

In splitting with Hochul, Jacobs, who has long sparred with his party’s left-wing base, joins some lawmakers who have recently said they will not back Mamdani; Reps. Laura Gillen (D-NY) and Tom Suozzi (D-NY), who represent Long Island swing districts targeted by Republicans, have criticized Mamdani’s far-left policies and confirmed this week that they will not be supporting his campaign.

Even as he declined to back Mamdani, the clear front-runner, Jacobs said he would not endorse any other candidates in the mayoral race, according to The New York Times. 

Mamdani’s opponents include Mayor Eric Adams, former New York Gov. Andrew Cuomo — both now running as independents — and the GOP nominee, Curtis Sliwa.

A spokesperson for Mamdani did not immediately respond to a request for comment.
