Immediate Resignation Following Controversy
Catherine Almonte Da Costa, appointed as the director of appointments for New York City Mayor-elect Zohran Mamdani, resigned on December 18, 2025, just one day after her appointment. This resignation came in response to the resurfacing of antisemitic social media posts dating back to 2011 and 2012, which were highlighted by the Anti-Defamation League (ADL). Da Costa's posts included derogatory remarks such as “money hungry Jews” and references to a train line as “the Jew train.” Following the ADL's public condemnation, Da Costa deleted her account and announced her resignation, stating that her past statements were not reflective of her current beliefs.
Official Statements & Responses
In her resignation statement, Da Costa expressed deep remorse, saying, “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.” Mamdani accepted her resignation, affirming that Da Costa had expressed her regret over her past statements. He stated, “Catherine expressed her deep remorse over her past statements and tendered her resignation, and I accepted.”
The ADL criticized Da Costa's posts, labeling them as “indefensible” and calling for explanations not only from her but also from Mamdani. They emphasized the need for accountability, especially given the rising antisemitism in the United States.
Background & Context
Zohran Mamdani, who is set to become New York City's first Muslim mayor on January 1, 2026, has faced scrutiny regarding his stance on antisemitism and Israel. His election campaign was marked by criticism for his refusal to condemn certain phrases associated with anti-Israel sentiments. The appointment of Da Costa, who was to lead talent recruitment in his administration, raised concerns among Jewish groups, particularly in light of the city's significant Jewish population.
Criticism & Opposition
The incident has sparked a broader discussion about Mamdani's administration and its commitment to combating antisemitism. Jewish leaders, including Halie Soifer, CEO of the Jewish Democratic Council of America, welcomed Da Costa's resignation, labeling her views as unacceptable. Critics have also pointed out that Mamdani's administration has previously faced allegations of antisemitism, including comments made by another staff member regarding Israel.
What's Next
As Mamdani prepares to take office, he faces the challenge of reassuring the Jewish community about his administration's commitment to fighting antisemitism. The ADL has initiated a “Mamdani Monitor” to track policies and personnel decisions within his administration. The fallout from Da Costa's resignation may influence Mamdani's approach to future appointments and his engagement with Jewish leaders.
