Zohran Mamdani’s swearing-in at City Hall on Thursday afternoon highlighted the full diversity of New York City and included a striking display of Jewish presence and pride during a historic change in leadership.

In a scene rich with symbolism, Sen. Bernie Sanders, who once ran to become the nation’s first Jewish president, administered the oath of office to the city’s first Muslim mayor as Mamdani placed his hand on a Quran.

Looking on from the dais was Sen. Chuck Schumer, the highest-ranking elected Jewish official in the United States. Jewish actor Mandy Patinkin, who hosted Mamdani for Hanukkah, led a musical performance with elementary school students from Staten Island. A bagel and lox schmear even got a mention during Mamdani’s inaugural remarks.

Mamdani’s vision of New York City

Mamdani, a democratic socialist and Israel critic whose surprise rise divided the city’s Jewish community, used his address to cast New York as a shared civic project shaped by its many languages and faiths. “The authors of this story will speak Pashto and Mandarin, Yiddish and Creole,” he said. “They will pray in mosques, at shul, at church, at Gurdwaras and Mandirs and temples — and many will not pray at all.”

The new mayor also mentioned Russian Jewish immigrants in Brighton Beach, who, along with other immigrant communities, came to America with a dream of a better life and nodded to his own upbringing deeply rooted in Jewish culture. “Where else could a Muslim kid like me grow up eating bagels and lox every Sunday,” Mamdani said, a line that drew cheers from the crowd.

Mamdani, a supporter of the Boycott, Divestment and Sanctions movement against Israel, drew louder applause when he acknowledged Palestinian New Yorkers in Bay Ridge, saying that under his tenure, they “will no longer have to contend with a politics that speaks of universalism and then makes them the exception.” Mamdani faced fierce backlash during the Democratic primary for defending the slogan “globalize the intifada,” used by some at the pro-Palestinian protests and perceived by many as a call for violence against Jews. In the inauguration crowd was Mahmoud Khalil, the Columbia University graduate who was held for deportation for his role in pro-Palestinian protests.

Mamdani also pledged to divest from city investments in Israel. This commitment could create a clash with Mark Levine, the incoming city comptroller, who has pledged to repurchase the bonds as part of the city’s portfolio. “This has been a rock-solid investment for decades,” he said. “Israel has never missed a bond payment, and a good, balanced portfolio should have global diversity.”

Levine, who is Jewish, took the oath of office on the Five Books of Moses, called the Chumash. “How remarkable is it that on these steps today, we have three swearings-in,” Levine said, “One by a leader using a Quran, one by a leader using a Christian Bible, and one by a leader using a Chumash or Hebrew Bible. I am proud to live in a city where this is possible.”

Mamdani orders new antisemitism office to stay open 

In a signing ceremony for his first three executive orders, Mamdani announced that he will keep open the recently-created mayor’s office to combat antisemitism. “That is an issue that we take very seriously,” he told reporters. Former Mayor Eric Adams used the office to counter antisemitism, including pursuing a measure adopting the controversial International Holocaust Remembrance Alliance definition of antisemitism, which considers most forms of anti-Zionism as antisemitic.

According to the executive order about the structure of the city government, the second measure Mamdani signed after the ceremony, the office will lead efforts to reduce antisemitism and anti-Jewish hate crimes using existing resources and act as a liaison between the city and the Jewish community on safety and security issues. It would regularly advise Mamdani on public education, tracking enforcement cases and reviewing city materials for bias.

Mamdani also issued an executive order revoking all previous executive orders issued by Adams after September 26, 2024, the day of his indictment on federal bribery and fraud charges. That includes the June 2025 measure adopting the IHRA antisemitism definition.

At the inauguration, Mamdani addressed skeptics directly, in a move to lower the temperature after a polarizing campaign. “I know there are some who view this administration with distrust or disdain, or who see politics as permanently broken,” he said. “And while only action can change minds, I promise you this: if you are a New Yorker, I am your mayor. Regardless of whether we agree, I will protect you, celebrate with you, mourn alongside you, and never, not for a second, hide from you.”

The Anti-Defamation League, which clashed with Mamdani during the election and launched a “Mamdani Monitor” to track and scrutinize the new administration’s appointments, said in a statement on Thursday that while holding him actions, the advocacy group will “stand ready to engage constructively” with the new mayor.

On City Hall steps and in the plaza 

The ceremony featured a benediction delivered by Imam Khalid Latif, executive director of the Islamic Center at NYU, who co-founded the NYU ‘Of Many’ Institute for Multifaith Leadership with Rabbi Yehuda Sarna. Appearing alongside the Imam was Rabbi Ellen Lippmann, founder and rabbi emerita of Kolot Chayeinu/Voices of Our Lives in Brooklyn and a board member of the progressive Jews For Racial & Economic Justice.

Levine, who speaks fluent Hebrew and Spanish, used the Hebrew terms for welcome and thank you in his remarks as the city’s new comptroller. “Welcome, everyone. What a joy that you came,” he said in Hebrew, after using similar terms in Spanish and Greek. “To those of you who don’t understand Spanish, Hebrew or Greek, welcome, thank you, and please download Duolingo,” he quipped.

Patinkin, an early supporter of Mamdani who appeared in a get-out-the-vote video with the candidate during the campaign, performed “Somewhere over the Rainbow” with the PS22 Chorus of Staten Island.

Rep. Jerry Nadler, co-chair of the Congressional Jewish Caucus, sat on the dais next to Schumer, who refused to endorse Mamdani during the election.

Among the 4,000 guests was Rabbi Moshe Indig, the leader of the Hasidic Satmar Ahronim faction who endorsed Mamdani in the general election. Also present were some Orthodox leaders who didn’t endorse and were close allies of Adams — Rabbi Chaim Dovid Zwiebel, executive vice president of Agudath Israel of America, and Josh Mehlman, head of the Flatbush Jewish Community Coalition.

Outside, a group of rabbis protested Mamdani’s swearing-in by displaying Israeli flags. It was led by Rabbi Avi Weiss, founding rabbi of the Hebrew Institute of Riverdale, and Rabbi Chaim Steinmetz of Congregation Kehilath Jeshurun on the Upper East Side. Both rabbis publicly opposed Mamdani during the election. In an interview with Talkline Network, a Jewish online radio, Steinmetz said it was a “demonstration of Jewish pride.” However, he said, New York Jews shouldn’t be fixated on Mamdani, they should assess his actions day by day.
