American Jewish organizations have responded to Zohran Mamdani's victory in the New York City mayoral election, expressing concerns about his past positions on issues important to the Jewish community. The Anti-Defamation League emphasized its expectation for Mamdani to oppose antisemitism in all forms and pledged to closely monitor his administration's actions regarding the safety and security of Jewish residents. The organization stated it would be relentless in its advocacy to protect Jewish New Yorkers. The Republican Jewish Coalition also criticized Mamdani's win, describing it as troubling for the city's Jewish population and for all residents, and accused Democrats of supporting a candidate they view as hostile to Jewish interests.
