New York City Mayor-elect Zohran Mamdani’s newly tapped director of appointments, Catherine Almonte Da Costa, resigned on Thursday afternoon after her history of antisemitic online posts — including complaining about “money hungry Jews” — was exposed.

“Catherine expressed her deep remorse over her past statements and tendered her resignation, and [Mamdani] accepted,” Dora Pekec, the mayor-elect’s transition team spokesperson, said in a statement to Jewish Insider.

Da Costa, who previously served as executive assistant to former Mayor Bill DeBlasio and was appointed by Mamdani on Wednesday, posted a series of antisemitic comments in 2011 and 2012, which were shared by the Anti-Defamation League. Da Costa’s account — and the posts, which had remained online — was deleted once the antisemitism watchdog published her posts on Thursday. 

“Money hungry Jews smh,” Da Costa posted on X in January 2011, according to screenshots. 

“Woo! Promoted to the upstairs office today! Working alongside these rich Jewish peeps,” she posted in June 2011.

In June 2012, Da Costa wrote that the “Far Rockaway train is the Jew train,” a reference to the neighborhood’s sizable Jewish population. 

Da Costa resigned on Thursday, saying that she “spoke with the Mayor-elect this afternoon, apologized, and expressed my deep regret for my past statements. 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. As this has become a distraction from the work at hand, I have offered my resignation.”

Sara Forman, executive director of the New York Solidarity Network, praised “cutting ties” with Da Costa as” the right thing to do,” but added that “had she said ‘Zionist’ instead of ‘Jew’ the response from the incoming Mamdani administration and the outcome we just witnessed would likely have been quite different.”

“This is why we have been telling Mr. Mamdani all along that all anti-Jewish rhetoric, including anti-Zionist dog whistles, cannot just be ‘discouraged,’ it must be rejected and condemned outright,” Forman said in a statement.

The Anti-Defamation League of New York and New Jersey condemned the posts on X before Da Costa’s resignation, writing that they “echo classic antisemitic tropes and otherwise demean Jewish people.” 

“We appreciate Da Costa has relationships with members of the Jewish community, but her posts require immediate explanation — not just from Ms. Da Costa, but also from the Mayor-Elect,” the ADL said in a statement. 

The recently unearthed posts come as several of Mamdani’s transition appointees have drawn scrutiny from Jewish leaders, who remain skeptical of the mayor-elect, who takes office on Jan. 1, and his commitment to fighting antisemitism. 

Among the most controversial of his appointments is Tamika Mallory, a former Women’s March leader who stepped down from its board amid allegations of antisemitism, to a newly established community safety committee.
