Prominent NYC rabbi rips Zohran Mamdani as a ‘danger’ to Jewish New Yorkers

The rabbi of a prominent Manhattan synagogue slammed Zohran Mamdani as a “danger to the security of the New York Jewish community” — as he urged congregants to back Andrew Cuomo for mayor instead.

“I believe Zohran Mamdani poses a danger to the security of the New York Jewish community,” Rabbi Elliot Cosgrove, of the renowned Park Avenue Synagogue on the Upper East Side, said during his Saturday sermon.

He said Mamdani refuses to denounce the phrase “Globalize the Intifada,” denies Israel’s legitimacy as a Jewish state, has vowed to arrest Israeli Prime Minister Benjamin Netanyahu and cited his “thrice repeated accusations of genocide” against Israel in Gaza at last week’s mayoral debate.

“For these and so many other statements … he is a danger to the Jewish body politic of New York City,” Cosgrove said.

Cosgrove also suggested congregants back ex-Gov. Cuomo, running as an independent, for mayor in the Nov. 4 election.

He said a vote for Republican candidate Curtis Sliwa guarantees Democratic nominee and front-runner Mamdani’s election.

“A vote for Sliwa, whatever his merits, is a vote for Mamdani,” Cosgrove said.

“There is a path to victory. No one should sit this one out. We must turn out to vote.”

Mayor Eric Adams, who recently said he won’t run for re-election, addressed Park Avenue Synagogue congregants Friday night, and expressed concern about Mamdani. He also later spoke privately with Cosgrove, a source said.

Adams said he will remain a staunch ally of the Jewish community after his term expires as a fellow New Yorker, a source who heard his speech said.
