The Democratic Socialists of America (DSA) chose controversial Twitch streamer Hasan Piker to host its official election night livestream, drawing a blunt response from Anti-Defamation League (ADL) CEO Jonathan Greenblatt, who accused the group of elevating rhetoric supportive of terrorism and antisemitism.

"Of all the people the DSA could have chosen to host its official election night livestream, it chose Hasan Piker, someone who proudly expresses support for terrorist organizations and traffics in antisemitism," Greenblatt wrote in a post on X. "Let that sink in. The DSA isn't distancing itself from this kind of rhetoric. It's elevating it." The DSA saw several of its endorsed or supported candidates win on Tuesday night, including Chris Rabb in Pennsylvania, Melat Kiros in Colorado, Donavan McKinney in Michigan, Claire Valdez in New York and Darializa Avila Chevalier in New York.

In his post, Greenblatt included a link to an ADL article statements by Piker that the organization criticized, including comments the ADL said said have "alluded to classic antisemitic tropes and conspiracy theories." The article contains some of Piker's more infamous remarks, such as when he referred to Orthodox Jews as "inbred" and his classification of Zionism as "an exterminationist ideology built around ethnoreligious supremacist values."

Piker did not hold back in his response to Greenblatt, writing, "Suck it Jonathan, your best friend Elon burned 450 million to lose races all over the country tonight you bald piece of s---!!!" The ADL did not immediately respond to Piker’s remarks about Greenblatt.

On Tuesday, Piker described the election as a "blue-clear apocalypse" as Democrats saw major gains in the House and Senate. Pike livestreamed for more than 13 hours, offering his signature political commentary as votes were tallied.

"Trumpism is dying, and I could not feel any better," Piker told his audience. At one point, he suggested, "Just imagine a world where Donald Trump is in f---ing prison."

He also gloated over Republicans' defeat, saying, "This is perhaps the worst possible scenario for the Republican Party, I think their odious agenda, their corruption, the destabilizing impact that they’ve had, the endless warfare and its consequences on the American economy, are finally coming back to bite them."

Ahead of the midterm elections, Piker drew attention in political circles as he interviewed and even campaigned with DSA-backed and DSA-aligned candidates. Piker came to national prominence after he campaigned with now-Senator-elect Abdul El-Sayed in Michigan. While his race was not explicitly DSA-backed, the organization said that El-Sayed "supports DSA priorities like Medicare for All." El-Sayed's decision to appear with Piker drew criticism.

The candidate appeared to distance himself from the streamer, holding no additional campaign events with him toward the end of the election cycle. This came after critics accused Piker of suggesting that Jewish Americans' support for Israel could lead to antisemitic violence against them.

"People don't f--- with Israel any longer. And if Jews in America keep putting this idea out there that they're singularly invested in Israel, eventually someone will come around and take action not against Israel, mind you, but against American Jews," Piker said during a Twitch stream in August.

While El-Sayed did not outright condemn the comments, he responded to Piker, saying, "I believe all Americans deserve the right to advocate for what they believe without fear of violence. This is particularly true for communities that have been intimidated for their beliefs in the past."

"My commitment to Jewish safety is the same as my commitment to the safety of my own daughters," he added. "Antisemitism is a scourge, and we need to address it in all its forms. And I stand against any rhetoric that puts the community at risk." Fox News Digital reached out to the DSA for comment but did not immediately receive a response.
