New York City Mayor-elect Zohran Mamdani’s incoming administration faced an early controversy when Catherine Almonte Da Costa, recently appointed as director of appointments, resigned just days after her selection. The resignation followed the resurfacing of social media posts from 2011 and 2012 containing antisemitic and anti-police remarks, prompting public backlash. The Anti-Defamation League (ADL) of New York and New Jersey condemned the posts, highlighting the harm caused by such statements regardless of their age. This incident immediately cast a shadow over Mamdani’s transition team, raising questions about internal vetting, judgment, and preparedness as the new administration prepares to assume office amid heightened scrutiny.

Reports indicate that Da Costa’s posts originated from a now-deleted X account and contained phrases widely recognized as antisemitic tropes, such as references to “money hungry Jews” and a Far Rockaway train labeled as “the Jew train.” The ADL emphasized that these remarks reflected harmful stereotypes historically used to demean Jewish communities. While acknowledging Da Costa’s personal connections to Jewish individuals, the organization maintained that such relationships do not excuse the comments or reduce their seriousness. The ADL’s statement underscored that harmful rhetoric carries lasting consequences, even when written years earlier, highlighting the ongoing relevance of accountability for public figures.

In response, Da Costa deleted her social media account and issued a public apology, expressing regret and remorse for her past actions. She personally contacted Mamdani to convey her feelings and framed her resignation as a means to prevent becoming a distraction during the administration’s transition. Da Costa described the posts as inconsistent with her current values and identity, noting her personal connection as a mother of Jewish children. Her statement emphasized sadness and shame over the resurfacing of her words, and she positioned stepping down as the responsible course of action under the circumstances.

Mayor-elect Mamdani accepted Da Costa’s resignation promptly, acknowledging her voluntary decision to step aside. While he did not elaborate extensively, the swift acceptance appears intended to contain the controversy and minimize disruption to the transition process. Da Costa had been responsible for overseeing recruitment for senior city government positions, a role crucial to shaping the leadership and culture of the new administration. Her departure leaves a significant vacancy at a politically sensitive moment, intensifying scrutiny of the team’s vetting procedures and decision-making processes.

This resignation represents the second significant challenge for Mamdani’s transition team in under a week. Earlier, Mamdani faced criticism for appointing Mysonne Linen, a convicted armed robber, to his transition team, a decision he defended as part of a commitment to rehabilitation and second chances. Critics argued that the appointment demonstrated poor judgment and raised concerns about governance standards. Together, these incidents have fueled scrutiny over the administration’s vetting process and strategic discipline, heightening concerns as Mamdani prepares to lead the nation’s largest city under intense public and political pressure.

Da Costa’s resignation also intersects with ongoing tensions between Mamdani and New York’s Jewish communities. Previously, Jewish leaders criticized him for not strongly condemning antisemitic rhetoric at protests, including the “Globalize the Intifada” slogan, which was linked to demonstrations following overseas attacks. Although Mamdani’s office rejected all hate speech, his reluctance to issue explicit denunciations drew criticism. Against this backdrop, Da Costa’s departure highlights the politically charged environment surrounding Mamdani’s mayoralty and underscores unresolved questions about leadership judgment, message discipline, and the challenges his administration will face in establishing credibility, accountability, and community trust from the outset.
