JTA — Five local rabbis are among the more than 400 New Yorkers tapped for New York City Mayor-elect Zohran Mamdani’s transition committees, the teams tasked with preparing his administration ahead of his January 1 swearing-in.

They include ex-Orthodox trans woman Abby Stein, who appeared in “Jews for Zohran” campaigns and shares the mayor-elect’s anti-Zionist outlook, on the health committee; Ellen Lippman, who recently retired from Kolot Chayeinu, the Brooklyn congregation where Mamdani attended Rosh Hashanah services, on the social services committee; and Rachel Timoner, whose Park Slope synagogue Congregation Beth Elohim hosted Mamdani for a meeting with congregants, and Jason Klein, who helms the LGBTQ synagogue Congregation Beth Simchat Torah, on the immigrant justice committee.

Rabbi Joseph Potasnik, executive vice president of the New York Board of Rabbis, sits on the emergency response transition committee. He is the only Jewish clergy member to join the transition committees of both Mamdani and Mayor Eric Adams, whom Mamdani unseated.

Adams’s 700-member transition team had a clergy committee with 16 rabbis from across denominations, including several from the city’s Modern and ultra-Orthodox communities. Mamdani does not have a clergy committee, and there are no Orthodox rabbis on any of his committees; during the campaign, he drew criticism from a wide array of rabbis over his anti-Israel stances and received little support from Orthodox voters.

The transition committees advise on policies, vet personnel, and broker relationships between the incoming administration and New Yorkers. Mamdani’s appointees range from traditional leaders, such as Kathryn Wylde, the longtime head of the city’s fundraising nonprofit, to those who traditionally have lacked power in the city — including representatives of the Democratic Socialists of America, the left-wing movement where Mamdani cut his teeth and which is vying to sustain influence as he assumes the mayorship. Mamdani has two committees, on worker justice and community organizing, that have not been part of a mayoral transition before.

Other notable Jews on the transition committees include Jonah Boyarin, a member of Jews for Racial and Economic Justice who helped craft city antisemitism trainings, on the community safety committee; Ruth Messinger, the former leader of American Jewish World Service, on the immigrant justice committee; Masha Pearl of the Blue Card, which supports needy Holocaust survivors, on the social services committee; and Mamdani’s high school teacher Marc Kagan on the transportation committee.

Also on the committees are a number of prominent New Yorkers who are Jewish but who have not made their Jewish identity a primary feature of their public personas.
