Catherine Almonte Da Costa, recently appointed as director of appointments in New York City Mayor-elect Zohran Mamdani's administration, has resigned following the emergence of old antisemitic social media posts. The posts, dating back to 2011 and 2012, contained offensive remarks about Jewish people. In a public statement, Da Costa apologized for her past comments, expressing deep regret and emphasizing that her words do not reflect her current beliefs. She noted that, as the mother of Jewish children, she feels profound remorse and has stepped down to avoid further distraction. Mayor-elect Mamdani accepted her resignation after she conveyed her remorse.
