Zohran Mamdani, the Mayor-elect of New York City, faces scrutiny after his top appointee, Catherine Almonte Da Costa, resigned following the resurfacing of antisemitic social media posts from her youth. Da Costa, appointed as director of appointments, had made inflammatory remarks such as 'Money hungry Jews smh' and called the Far Rockaway train 'the Jew train' when she was 18, over a decade ago. These posts, revealed by the Anti-Defamation League and reported by the Judge Street Journal, prompted her immediate resignation and public apology. Mamdani expressed regret for not vetting her thoroughly and accepted her resignation, emphasizing the administration’s commitment to high standards and accountability. The incident has raised concerns about the transition’s vetting process and the administration’s ability to address deep divisions, especially within the Jewish community, which has expressed skepticism due to Mamdani’s past criticisms of Israel. Da Costa, who later married a Jewish man and has Jewish children, stated her remorse and indicated her past comments do not reflect her current beliefs. The controversy underscores ongoing challenges in political vetting and the importance of scrutinizing candidates’ histories, especially when highly scrutinized roles are involved.
