A conservative Jewish professor who rejected Hitler comparisons now invokes one — for Tucker Carlson

(JTA) — In the lead-up to the 2024 presidential election, Jeffrey Lax, a descendent of Holocaust survivors who has lobbied against antisemitism at the college where he teaches, criticized liberals who compared Donald Trump to Hitler.

Now Lax, a law professor who defines himself as center-right and appears frequently on Newsmax and Fox News, is rethinking the idea of modern-day Hitler comparisons. In fact, he’s ringing that bell on a key Trump ally: Tucker Carlson.

“I never, ever, thought this day would come, but for the first time in my life, I am going to compare a human being to Adolph Hitler,” Lax tweeted on Friday. “Understand that I am the grandchild of 4 Holocaust survivors. I’ve spent a lifetime urging people NOT to compare anyone to Hitler. But… Tucker Carlson’s views, rhetoric, and influence remind me of Adolph Hitler.”

Lax was responding to Vice President JD Vance’s favorable comments about the interview Carlson, a far-right pundit, did last week with Mike Huckabee, the U.S. ambassador to Israel. The interview ignited new allegations of antisemitism, but Vance did not suggest any concern. That, Lax says, is a big problem.

“This situation is as dead serious as a heart attack and with @JDVance now expressly and abhorrently legitimizing Carlson’s views, we are in a national Antisemitism State of Emergency,” Lax continued.

It was a dramatic outlay of angst about antisemitism on the right for a figure who has campaigned against left-wing anti-Israel activism at the City University of New York, where he teaches. But Lax said in an interview that he could not remain silent.

“For me to get to this point, it had to be something that was so deeply disturbing on many levels,” he said. Carlson’s call for genetics testing for Jews, he said, crossed that line. “If anything I’ve ever heard is Hitler-esque, when you talk about Jews having to prove that they’re Jews with DNA — if DNA testing was available in the days of Hitler, do you not think that Hitler would have used it?”

Lax emphasized that he was speaking specifically of “early Hitler, the early years, before he took power, before he actually, physically caused anybody to be killed. I’m talking about the rhetoric. He could’ve been stopped at that point. People didn’t take Hitler seriously.”

While Lax has criticized Carlson before, he has in the past refrained from extending those critiques to Vance — despite a mounting record of the vice president minimizing antisemitism on the right. “I’ve had suspicions about Vance for a long time,” Lax said. “I wanted to be sure.”

Vance’s defense of Carlson’s interview provided the certainty he needed.

“Is he out of his mind?” Lax said. “By saying something like that, you are saying that what Tucker is saying is legitimate and needs to be discussed, including that Jews should have genetic testing done to be sure that they’re Jewish and have right to the land.” He described such a belief as “brain rot.”

Lax joins a growing line of other Jewish conservatives who have expressed alarm about Vance and his closeness to the White House. They include far-right activist Laura Loomer; conservative columnist and Newsweek editor Josh Hammer; Israeli conservative luminary Yoram Hazony; Orthodox right-wing pundit Ben Shapiro; Rep. Randy Fine; pro-Israel activist groups StandWithUs and StopAntisemitism; and publications with a conservative-friendly pro-Israel bent including Tablet, The Free Press and Commentary.

Their alarm comes as Carlson builds a formidable political network of his own ahead of the midterms, made up of figures with growing sway over young voters. He has given friendly interviews to several outsider GOP candidates, including Florida gubernatorial candidate James Fishback, lover of antisemitic memes; Texas congressional candidate and pardoned Jan. 6 rioter Ryan Zink; U.S. Senate candidate Paul Dans, who is challenging pro-Israel Sen. Lindsay Graham; and Iowa gubernatorial candidate Zach Lahn, who used his Carlson interview to disparage non-Christian elected officials.

Influential figures identified with the left are also increasingly coming to Carlson’s side on Israel and Jews. “Hey bitch, the goyim are waking the fuck up. Deal with it,” Ana Kasparian, a co-host on the progressive online network The Young Turks, tweeted as part of an extended defense of Carlson this week.

Amid a backlash, the next day Kasparian doubled down: “I do not regret this comment. I don’t apologize,” she tweeted. “Israel is evil, genocidal and has destroyed our country. They’re about to drag us into another war and all we hear from Israelis and their braindead supporters is ‘ANTISEMITE’ if you disagree with Israel’s agenda.” (Kasparian’s Young Turks colleague, Cenk Uyghur, is a regular Carlson guest.)

While antipathy toward Carlson has been all but fully cemented for Jews on both sides of the aisle, not every Jewish conservative has turned on Vance.

Matt Brooks, director of the Republican Jewish Coalition, harshly criticized Carlson and his defenders last fall after the pundit interviewed white nationalist Nick Fuentes, and the group’s most recent conference was marked by repeated denunciations of Carlson. Yet RJC has refrained from publicly pointing the finger at Vance, and its posts about him to date are uniformly complimentary — as on Thursday, when the group retweeted a speech from the vice president’s X account about Democrats and affordability.

A request for comment to the RJC was not returned.

“That is outrageous that the RJC would not criticize Vance,” Lax said. “That is self-destructive. That is insane.”

Also treading carefully on Vance are many establishment Jewish groups. Neither the Anti-Defamation League nor its CEO, Jonathan Greenblatt, has publicly criticized the vice president since February 2025, when the ADL’s X account docked him for meeting with the head of Germany’s far-right AfD party. The American Jewish Committee, similarly, has critiqued Carlson’s rhetoric in the past but remained muted on Vance as he’s increasingly clarified that he believes the pundit is a valuable part of the Republican coalition. Comments to representatives for the two organizations were not returned.

Because Lax runs a registered nonprofit, the Zionist group S.A.F.E. Campus, he said he was hesitant to comment too specifically on electoral politics. But he said he believes Jews on the right are “coming around” to the problem of antisemitism on their side. And he’s deeply concerned about Vance running for president in 2028 without having distanced himself from Carlson.

“I could never support a candidate who says we need to have a conversation about genetically testing Jews,” Lax said. “What Vance said, I think people’s eyes popped out of their heads.”

And, despite his earlier defenses of Trump, he said the president must more forcefully condemn Carlson and Vance’s rhetoric now. “He can’t have his vice president say that it is an important conversation that we talk about genetically testing Jews to see if they come from Abraham,” Lax said. Vance himself once compared Trump to Hitler, prior to being chosen as his running mate.

Lax is also reflecting more on his 2024 piece decrying Trump-Hitler comparisons. If the president doesn’t issue a more forceful condemnation of his party’s antisemitic wing in the next month, the professor said, ”I may very well change my mind.”

By Friday afternoon, he had drawn a possible line in the sand, tweeting a call for Trump to demand Vance’s immediate resignation.

“Enough. This is a National Antisemitic State of Emergency. Only Trump can end it. And he must do so now,” Lax wrote. “It starts by booting JD and cutting Tucker out from all conservative and Republican orgs.”
