The Washington Post got the What’s App transcripts and multiple participants confirming the content of the chat. They then asked the mayor’s office about it and the spokesperson said that the question was anti Semitic.

Correction, they asked about the Zoom meeting (which they had the transcript and on the record participants):

Asked about the Zoom meeting with chat group members, the mayor’s office did not address it directly, instead sharing a statement from deputy mayor Fabien Levy noting that New York police entered Columbia’s campus twice in response to “specific written requests” from university leadership. “Any suggestion that other considerations were involved in the decision-making process is completely false,” Levy said. He added, “The insinuation that Jewish donors secretly plotted to influence government operations is an all too familiar antisemitic trope that the Washington Post should be ashamed to ask about, let alone normalize in print.”
