Zohran Mamdani, the Democratic nominee for mayor of New York City, expressed disagreement on Thursday with comments by Hasan Piker, a far-left streamer who has said “America deserved 9/11,” after several months in which the state assembly member had declined to condemn such rhetoric.

“I find the comments that Hasan made on 9/11 to be objectionable and reprehensible,” Mamdani said during the first general election debate on Thursday night, where he traded barbs with former New York Gov. Andrew Cuomo, who is trailing in the polls as he mounts an independent run following his primary loss to Mamdani in June.

Still, Mamdani, a 33-year-old democratic socialist, defended his decision to appear on Piker’s show for an extensive interview during the primary — even as the streamer has otherwise frequently stirred controversy for using antisemitic rhetoric in his commentary on Israel and Jewish issues. 

“I also think that part of the reason why Democrats are in the situation that we are in, of being a permanent minority in this country, is we are looking only to speak to journalists and streamers and Americans with whom we agree on every single thing that they say,” Mamdani argued, while making no mention of Piker’s antisemitic comments. “We need to take the case to every person, and I am happy to do that.”

Piker has faced criticism for justifying Hamas’ Oct. 7, 2023, attacks and forcefully denying some of the terror group’s atrocities — including widespread reports of sexual violence. In one notable stream last year, Piker said “it doesn’t matter if rapes f***ing happened on Oct. 7,” while adding that “the Palestinian resistance is not perfect.” He has also described Orthodox Jews as “inbred” and compared Zionists to Nazis, among other slurs seen as antisemitic.

Elsewhere during the debate, Mamdani, an outspoken critic of Israel who was arrested in October 2023 during a ceasefire demonstration outside the Brooklyn home of then-Senate Majority Leader Chuck Schumer (D-NY), declined to confirm that he would not participate in protests if he is elected mayor. “The important thing is to lead from City Hall,” Mamdani said. “That’s what I’ll be doing.”

Mamdani had faced intense backlash before the debate for comments during a Fox News interview released on Wednesday in which he avoided directly answering a question about whether Hamas should disarm and relinquish its leadership role in Gaza. He clarified at the debate that Hamas, as well as “all parties,” “should lay down” their arms but did not comment on its future role in the conflict.  

“I’m proud to be one of the first elected officials in the state who called for a ceasefire, and calling for a ceasefire means ceasing fire,” Mamdani said. “That means all parties have to cease fire and put down their weapons. And the reason that we call for that is not only for the end of the genocide, but also an unimpeded access of humanitarian aid.”

He added that “we also have to ensure that [the ceasefire] addresses the conditions that preceded this, conditions like occupation, like the siege and apartheid, and that is what I’m hopeful for.”

Mamdani, who has seen mixed results in his continued outreach to the Jewish community, also once again refused to condemn the phrase “globalize the intifada” — even as he reiterated that it “evokes many painful memories” for Jewish voters and reiterated he will “discourage” its usage.
