🚨 BREAKING: One day after being hired by Mayor-elect Zohran Mamdani, Catherine Almonte Da Costa submitted her resignation after antisemitic statements in old Twitter posts dating back to 2011 surfaced Thursday.

Mamdani transition sources tell NBC New York that he and his transition were unaware of the posts when they appointed Da Costa Wednesday.

When Mamdani put Da Costa in charge of hiring for the City she pledged to recruit diverse talent.
