Zohran Mamdani's newly appointed director of appointments, Catherine Almonte Da Costa, resigned after antisemitic social media posts from over a decade ago resurfaced. The posts, which included derogatory remarks about Jewish people, were condemned by the Anti-Defamation League and led to swift backlash. Da Costa, who previously worked in city government and is married to a Jewish man, issued a public apology expressing deep regret for her past comments, stating that they do not reflect her current beliefs. Mamdani accepted her resignation, emphasizing her remorse, while both declined to offer further comment.
