The American Jewish Committee raised alarms on Friday about Zohran Mamdani’s “continued use of problematic rhetoric as it relates to Israel and Jews” and called on the Democratic nominee for mayor of New York City to “change course” as he prepares for the Nov. 4 election. 

In a lengthy statement, the nonpartisan organization cited, among other things, Mamdani’s repeated claim that Israel has committed genocide in Gaza, which the AJC called “unequivocally false and dangerous.” The charge “has not been proven in any international court” and “gives fodder to those who continue to use Israel’s self-defensive actions as an excuse to threaten and attack Jews,” the group said.

The AJC also criticized Mamdani’s refusal to recognize Israel’s right to exist as a Jewish state, saying that he is upholding an “unacceptable double standard” in his assessment of the region. “Israel is surrounded by Muslim countries,” the group wrote, “yet Mamdani does not continuously suggest that any of those nations should not exist as they are.”

And the organization took issue with what it characterized as Mamdani’s “lack of consistent moral clarity on Hamas,” pointing to a Fox News interview on Wednesday in which he sidestepped a question about whether Hamas should disarm and relinquish its leadership role in Gaza.

Mamdani, a democratic socialist assemblyman who has long been involved in anti-Israel activism, later clarified during the first general election debate on Thursday that Hamas “should lay down” its arms, but he did not share his views on its future role in the conflict.

The AJC, which has also recently highlighted concerns about Mamdani’s refusal to condemn calls to “globalize the intifada,” said in its statement that it feels “compelled to speak out when public figures use rhetoric or endorse policies that harm Jews.”

It urged Mamdani “to engage in dialogue and consultation with organizations and segments of the mainstream New York Jewish community,” with which he has had a tense relationship throughout the campaign and as an elected official in Albany.

“By continuing to prioritize anti-Zionist synagogues and groups, Mamdani ignores the perspectives and concerns of the vast majority of Jewish New Yorkers,” the group said.

Mamdani, who has stepped up his Jewish outreach efforts in recent weeks with limited success, has rejected claims that his views fuel antisemitism and vowed to increase funding to counter hate crimes by 800% if he is elected.

“One of the most meaningful experiences I’ve had over the course of this campaign has been the conversations I’ve had with Jewish New Yorkers,” Mamdani said at the debate on Thursday.

A spokesperson for Mamdani did not respond to a request for comment.
