New York City Mayor Zohran Mamdani, who built his political brand on fiery anti-Israel rhetoric and once pledged to arrest Israeli Prime Minister Benjamin Netanyahu, has quietly declined to join street protests against Netanyahu's visit, a reversal that exposes the gap between campaign bluster and governing reality.
The shift is striking for a mayor who rode progressive activism into City Hall. Mamdani's earlier posture on Netanyahu was unambiguous: he wanted the Israeli leader detained. Now, facing the actual obligations and diplomatic constraints of running America's largest city, he has gone silent on the matter while protesters fill the streets without him, Religion News Service reported.
The about-face arrives at a moment when Mamdani can least afford it. His young administration has lurched from one self-inflicted crisis to the next, and the Netanyahu episode adds a credibility problem to an already long list of operational failures and personnel embarrassments.
The most damaging recent episode landed just weeks before Mamdani took office. Catherine Almonte Da Costa, hand-picked by Mamdani to serve as New York City's director of appointments, the person responsible for vetting every hire in the incoming administration, resigned within hours of her own antisemitic social media posts surfacing publicly.
The posts, dating to 2011 and 2012, included a tweet reading "Money hungry Jews smh" and references to a "Jew train" and "rich Jewish peeps." Da Costa also posted derogatory comments about the NYPD, including references to "NYPD piggies" and past support for defunding the department by $1 billion, the New York Post reported.
The Anti-Defamation League's New York and New Jersey chapter publicly demanded answers from Mamdani's transition team after flagging the posts. The ADL called Da Costa's language "indefensible."
Da Costa deleted her X account and resigned the same day. Mamdani accepted.
In a statement, Mamdani said Da Costa "expressed her deep remorse over her past statements and tendered her resignation, and I accepted." Da Costa, for her part, offered a carefully worded apology, as AP News reported:
"These statements are not indicative of who I am. As the mother of Jewish children, I feel a profound sense of sadness and remorse at the harm these words have caused."
The ADL had already announced it was building a tool to "track and monitor policies and personnel" hired by Mamdani following his election, a level of institutional scrutiny rarely directed at an incoming mayor before he even takes office.
Da Costa's appointment and rapid exit raised an obvious question: who vetted the person in charge of vetting? The answer, based on the timeline, appears to be nobody. Mamdani named Da Costa on a Wednesday. By Thursday, she was gone. The ADL did not need subpoena power or a forensic investigation to find the posts. They were on a public social media account.
The incident was not an isolated stumble. Mamdani's transition and early administration have drawn repeated scrutiny for controversial personnel choices that suggest ideology, not competence, is driving hiring decisions.
Fox News noted the resignation came less than two weeks before Mamdani was set to be sworn in as mayor, a period when an incoming administration typically projects stability and readiness, not damage control over hateful social media posts from its own appointees.
For a mayor who campaigned on moral clarity about bigotry, the failure to catch antisemitic posts from his own director of appointments is more than an embarrassment. It is a direct contradiction of his stated values.
Mamdani's retreat on the Netanyahu question fits the same pattern: bold words followed by quiet reversals when consequences arrive. As a state legislator and mayoral candidate, Mamdani positioned himself as one of the most vocal anti-Israel elected officials in New York. His pledge to arrest Netanyahu was a centerpiece of that brand.
That posture drew serious blowback. Israel's UN ambassador publicly demanded Mamdani face consequences over his protest push, the kind of diplomatic pressure that a state assemblyman can shrug off but a sitting mayor of a global financial capital cannot.
Now in office, Mamdani has apparently calculated that joining street protests against a visiting head of state carries risks he did not have to weigh as a backbench legislator. So the arrest talk has stopped. The protest invitations go unanswered. The activists who helped elect him march without their champion.
None of this means Mamdani has moderated. His administration's other controversies suggest the opposite. City Hall has faced questions about concealing a two-hour 911 outage from the public, a lapse that put lives at risk and raised serious transparency concerns about how his team handles operational failures.
Mamdani's first months in office have been defined less by policy achievements than by a series of unforced errors that call into question whether his team is capable of managing a city of eight million people.
Beyond the Da Costa fiasco and the Netanyahu reversal, his administration has drawn scrutiny for running a 200-person influencer operation on encrypted Signal, raising questions about whether city records laws are being circumvented to shield official communications from public accountability.
The ADL's decision to build a permanent monitoring apparatus for Mamdani's personnel choices is itself a remarkable development. Major civil rights organizations do not typically treat a newly elected mayor as a subject requiring ongoing surveillance. That the ADL felt compelled to do so, and that events immediately proved the concern justified, tells New Yorkers something about the kind of administration they are getting.
Mamdani's defenders might argue that Da Costa's posts were a decade old and that people change. But the posts were public, easily discoverable, and full of language that any competent vetting process would have flagged in minutes. The failure was not one of forgiveness. It was one of basic diligence.
And the Netanyahu reversal is not about a change of heart on Israel policy. It is about a politician who made promises he either could not or would not keep once the weight of office settled on his shoulders.
Governing New York City has a way of humbling leaders who mistake slogans for strategy. Mamdani is learning that lesson faster than most, and the people who believed his campaign promises are the ones paying the price.
