Resignation of Mamdani's Appointee Over Antisemitic Remarks

Catherine Almonte Da Costa, an appointee in New York City Mayor Zohran Mamdani's administration, resigned after antisemitic comments she made in 2011 and 2012 resurfaced. Da Costa was selected to lead the office of appointments, focusing on talent recruitment strategy, but her past social media posts led to significant backlash, prompting her resignation on December 18, 2022. The controversy escalated when New York Magazine edited her out of a cover photo featuring Mamdani and his inner circle, deeming it inappropriate to include her image.

Zohran Mamdani, who was sworn in as New York City's first Muslim mayor on January 1, 2026, won the election by addressing issues of affordability and garnering support from progressive voters, including young Jewish constituents. His administration's focus on inclusivity and social justice has been met with both support and scrutiny, particularly regarding his stance on Israel and Palestine.

In response to the controversy, Da Costa expressed "deep regret" for her past statements, emphasizing that they do not reflect her current beliefs. “As the mother of Jewish children, I feel a profound sense of sadness and remorse at the harm these words have caused,” she stated. Mayor Mamdani accepted her resignation, acknowledging her regret and the impact of her comments.

The Anti-Defamation League (ADL) played a significant role in amplifying the issue, as they uncovered and circulated Da Costa's posts. Following the incident, the ADL announced the launch of a "Mamdani Monitor," aimed at tracking the mayor-elect's policies and personnel appointments, including a tip line for reporting antisemitism related to City Hall.

The incident has raised concerns about antisemitism within Mamdani's administration, particularly given his outspoken views on Israel's actions in Gaza. Critics argue that the appointment of individuals with problematic pasts could undermine the administration's credibility and alienate Jewish constituents. Mamdani has faced scrutiny for his stance on Israel, which some perceive as antisemitic, despite his efforts to clarify his position and maintain support from progressive Jewish voters.
