J Street is defending its decision to co-sponsor the College Democrats of America convention after critics accused the liberal pro-Israel group of endorsing the anti-Zionist streamer Hasan Piker, who was a featured speaker at the event.

In a statement posted Monday, J Street said its campus arm, J Street U, spent “a couple thousand dollars for an exhibit table” and had “no role in choosing speakers, no approval over the program and no say in who was invited to address the conference.”

“J Street disagrees with much of what Hasan Piker says and with the way he says it. We won’t hesitate to say so,” the group wrote on social media in a statement first authored by its president, Jeremy Ben-Ami. “But we also reject the notion that the right answer to his invitation is to abandon the very spaces where the next generation of Democratic leaders is debating these issues.”

The convention, which was held in Washington, D.C., from Thursday to Sunday, featured a host of speakers, including Rep. Jamie Raskin, a Jewish Democrat in Maryland; Randi Weingarten, the Jewish president of the American Federation of Teachers; and the democratic socialist Colorado congressional candidate Melat Kiros.

The statement followed blowback from several pro-Israel commentators, including author and podcaster Dan Senor, former Auburn basketball coach Bruce Pearl and Israel historian Sara Yael Hirschhorn, who all said it was inappropriate for a Jewish group to share a tent with an anti-Israel figurehead.

“If J Street knew that he is one of the key speakers and still sponsored this event it’s a new low,” Nadav Pollak, a lecturer on Middle East affairs at Reichman University, wrote in a post on X. “An organization that claims to be ‘pro-Israel’ sponsors an event with one of the most anti-Israel speakers. Shameful.”

Sen. John Fetterman, a Pennsylvania Democrat and pro-Israel stalwart, also took aim at J Street in an interview on Fox News Sunday.

“Even Jewish kinds of organizations like J Street are doing events with people like Hasan Piker,” Fetterman said. “Hasan Piker, I mean, how can you embrace people like that?”

The online row came amid a growing divide over whether Jewish groups should engage in progressive spaces where anti-Zionist voices have become increasingly influential, or withdraw from them altogether.

J Street U, the group’s college arm, has faced resistance from both directions in recent months, including at Sarah Lawrence College, where the student senate rejected an application for a college chapter over its Zionist identity, even as J Street faced criticism from the right for newly endorsing an end to U.S. military aid to Israel.

Piker, who has drawn fierce condemnation for his rhetoric on Israel and campaigned alongside democratic socialist congressional candidates across the country, used his remarks at the convention to call for an end to U.S. military aid to Israel.

“No more to the Democrats who compromise, who conciliate, and who betray us,” Piker told the crowd during his remarks. “No more to the fascist reactionaries, but no more to the Democrats who will collaborate and cooperate with the fascists, who will fund ICE, who will fund Israel, who will help poison the planet, who will stiff workers and help bosses.”

In a livestream Sunday, Piker defended J Street from the blowback, saying, “While I have my disagreements with J Street, they’re not insane. Okay, they’re not as insane as like the AIPAC-backed Democrats are. They can read the room.”

“Ultimately, J Street understands that there is a a much wider diversity of opinion on the issue of Israel on the Democratic Party side, and … if they want to continue to maintain a level of support for Israel amongst Democrats, they have to allow people like myself to be a part of this equation because I’m far closer to the average person’s perspective than they are,” Piker said, adding that he had been trying to have a “conversation” with Ben-Ami.

J Street said it was committed to advocating for its perspective in ideologically diverse spaces and characterized its presence at the College Democrats convention as a bulwark against extremism.

“Our mission is not to preach to the converted. It is to ensure that a pro-Israel, pro-peace voice is heard wherever the future of American politics is being shaped,” it said. “If we leave those conversations to others, we shouldn’t be surprised when the loudest and most polarizing voices dominate them.”
