(JTA) — New York City Mayor-elect Zohran Mamdani’s pick for a crucial City Hall position resigned on Thursday, shortly after her history of antisemitic posts on X came to light.
Mamdani had announced his appointment of Catherine Almonte Da Costa as director of appointments, responsible for staffing City Hall, on Wednesday. But on Thursday, several posts on X where she peddled age-old antisemitic stereotypes were published by the Judge Street Journal, a Substack about New York City politics.
“Money hungry Jews smh,” Da Costa posted on a now-deleted account on X in January 2011, when she 19 years old.
In another post from June 2012, she wrote, “Far Rockaway train is the Jew train,” appearing to reference the large Jewish communities off the line.
The Judge Street Journal also highlighted posts that suggested an antipathy to white men by Da Costa, who has worked in diversity, equity and inclusion roles in multiple companies.
As a firestorm grew, Da Costa said she would step down.
“I spoke with the mayor-elect this afternoon, apologized, and expressed my deep regret for my past statements,” she said in a statement shared by the Mamdani transition team. “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. As this has become a distraction from the work at hand, I have offered my resignation.”
Mamdani released a statement of his own. “Catherine expressed her deep remorse over her past statements and tendered her resignation, and I accepted,” he said.
The incident came as Mamdani’s election has roiled the city’s Jewish community, with many expressing fear and discomfort over the mayor-elect’s history of anti-Israel rhetoric and policies. He has emphasized that he aims to make the city safe and welcoming for all of its residents, including Jews, and has condemned antisemitic rhetoric and displays since his election.
Still, his transition period has been dotted with tensions, including While Mamdani has made inroads in the city’s Jewish community since election night last month, the appointment of an official with a visible history of antisemitic rhetoric could pose another hurdle for his incoming term.
The New York and New Jersey branch of the Anti-Defamation League, which launched what it is calling a “Mamdani Monitor” following November’s election, called Da Costa’s posts “indefensible” in a post on X.
“We appreciate Da Costa has relationships with members of the Jewish community,” the group tweeted. “But her posts require immediate explanation — not just from Ms. Da Costa, but also from the Mayor-Elect.”
Several Jewish leaders praised Da Costa’s resignation.
The CEO of the Jewish Democratic Council of America, Halie Soifer, welcomed the news of in a statement Thursday evening.
“Glad to see that Catherine Almonte Da Costa has resigned,” said Soifer in a statement. “The views she expressed are unacceptable and intolerable. Especially at a time of rising antisemitism, she had no place in the mayor’s office of the city with the largest Jewish population in the world.”
Sara Forman, executive director of the New York Solidarity Network, which backed Mamdani’s leading opponent in the election, praised “cutting ties” with Da Costa as” the right thing to do.” But Forman speculated that “had she said ‘Zionist’ instead of ‘Jew’ the response from the incoming Mamdani administration and the outcome we just witnessed would likely have been quite different.”
Da Costa’s husband, Ricky Da Costa, is a deputy in the office of Comptroller Brad Lander, Mamdani’s most prominent Jewish backer during the campaign. He is Jewish and posted on X for the first time in more than a year in a half on Thursday afternoon, in response to the criticism of his wife.
“I don’t come back to this awful place much these days but as the Jew who married Cat, I can guarantee she has grown so much since some dumb tweets when she was 19,” he wrote. “Her remorse, like everything else about her, is deeply genuine & she works so hard for a NYC where everyone is safe.”
