Appointee quits over antisemitic posts

One of New York City Mayor-elect Zohran Mamdani ’s appointees has resigned over social media posts she made more than a decade ago that featured antisemitic tropes, Mamdani’s office said Thursday.

In a statement, Catherine Almonte Da Costa, who was tapped this week to join the incoming administration, said she expressed “deep regret” for the posts, which date back to 2011 and 2012 and were recently shared online by the Anti-Defamation League.

“These statements are not indicative of who I am. As the mother of Jewish children, I feel a profound sense of sadness and remorse at the harm these words have caused,” Da Costa said.

She had been selected to lead Mamdani's office of appointments, handling “talent recruitment strategy." Da Costa worked in the office more than a decade ago and more recently held roles at a private communications firm and at Sotheby’s, the mayor-elect's office said.
