Conservative New York radio host Sid Rosenberg ignited another political firestorm Monday night after claiming he sent a “spy” to a Shavuot celebration hosted by New York City Mayor Zohran Mamdani at Gracie Mansion, intensifying an already bitter feud over the mayor’s stance on Israel and his relationship with the city’s Jewish community.
The event, organized in recognition of the Jewish holiday of Shavuot, drew attention because Mamdani has faced repeated accusations from critics who claim his rhetoric regarding Israel has crossed into anti-Semitism. Those accusations have followed him since before arriving at Gracie Mansion and continue to fuel deep political divisions inside New York City.
Throughout his campaign, Mamdani insisted he would protect Jewish New Yorkers just as he would members of any other faith community. Still, many critics remain unconvinced, arguing that his past comments and political positions on Israel have alienated portions of the city’s Jewish population during a period of heightened global tensions and rising fears about anti-Semitism.
Ahead of Monday’s gathering, Rosenberg launched a furious social media attack on both the mayor and Jewish attendees who chose to participate in the event.
“Any Jew that is at Gracie Mansion tonight celebrating Shavuot with this Radical Islam, terrorist sympathizing Mayor is a disgrace and a fucking sellout!” Rosenberg wrote online.
The radio host went on to claim he had a “spy” inside the gathering who reported that many Orthodox Jewish attendees — which Rosenberg referred to as “black hats” — appeared to be enjoying the celebration.
Rosenberg further accused Mamdani and his wife of deliberately offending Jewish residents by connecting the event to Nakba Day, a politically charged commemoration observed by Palestinians and their supporters. He also complained about the timing of the gathering, saying the mayor “purposely did it on Shabbat to really fuck with us.”
The comments underscored how emotionally charged debates surrounding Israel and the Middle East have increasingly spilled into local American politics, particularly in cities like New York with large Jewish and Muslim populations. While leaders across the political spectrum frequently call for unity and tolerance, public discourse has often grown more heated as overseas conflicts continue to inflame passions at home.
Mamdani’s critics have repeatedly pointed to his comments and activism related to Israel as evidence of hostility toward Jewish people, while supporters argue criticism of Israeli government policy should not automatically be equated with anti-Semitism. The mayor has maintained that he supports protecting Jewish residents and safeguarding religious freedom for all New Yorkers.
Rosenberg, however, has remained one of the mayor’s loudest and most aggressive critics.
In recent weeks, the radio personality has repeatedly targeted Mamdani on social media. Earlier this month, Rosenberg even accused the mascots of the New York Mets of anti-Semitism after they participated in a photo opportunity with the mayor.
The escalating rhetoric reflects the increasingly personal and combative nature of political debate surrounding Israel-related issues in the United States. Even cultural and civic events that once may have been viewed as routine celebrations are now becoming flashpoints in broader ideological battles over identity, foreign policy, and community loyalty.
As tensions over the Middle East continue reverberating through American politics, disputes like this one highlight how conflicts overseas can deepen divisions at home, with public officials, activists, and media figures all competing to define where criticism ends and discrimination begins.
