Nine months after the Heritage Foundation came under fire for defending Tucker Carlson’s friendly interview with a neo-Nazi, the conservative think tank is facing fresh scrutiny over accusations that it has enabled an extreme culture in which new hires feel free to question the Holocaust and to engage in historically revisionist debates about World War II, with no apparent internal policing from leadership.

Former Heritage employees, who had been part of a mass staff exodus stoked by its president’s refusal to disavow Carlson for hosting the neo-Nazi influencer Nick Fuentes on his podcast last October, told The New York Times Magazine in a newly published investigation that they encountered troubling debates during their time at the organization over issues like “whether the Holocaust happened or not” and “who was the bad guy and who were the good guys” in the war against Hitler.

Andrew Hale, a trade policy analyst at Heritage who left in January to join a rival think tank launched by former Vice President Mike Pence, recalled that prior to departing he had found new hires were fixated on antisemitic conspiracy theories about the Holocaust and Israel of the sort popularized by Fuentes, Carlson and Candace Owens, the extreme-right podcast host.

Hale confirmed to Jewish Insider in an interview on Wednesday that new, particularly younger, staffers at Heritage “openly said things which were antisemitic, whether they realized it or not,” crediting their views to an obsession with far-right social media channels. 

“The Heritage Foundation had an opportunity to combat antisemitism and misogyny but instead they chose to hire people with these views,” Hale argued, while claiming that the think tank’s “original goals have been subverted under the current leadership” and is now “a force for antisemitism and misogyny.”

Brian Phillips, a Heritage spokesperson, called Hale’s claim about the Holocaust debate “absurd” but did not address related allegations from former staffers, whom the think tank sought to discredit as “self-serving, bitter and vindictive” in a statement to the Times Magazine. 

“There is no debate at the Heritage Foundation whether the Holocaust happened and our record opposing antisemitism is long, consistent and public,” he said in a brief email statement to JI, sharing a link to a page on Heritage’s website detailing such efforts.

The foundation, which had long been influential to Republican administrations, has found itself on the defensive after its president, Kevin Roberts, posted a controversial video to social media last fall in which he dismissed Carlson’s critics as part of a “venomous coalition,” among other terms widely interpreted as antisemitic tropes.

“Heritage is catering to a conspiratorial streak popular with Gen Z Republicans, perhaps out of the belief that it’s the future of the party,” Daniel Samet, a fellow with the conservative American Enterprise Institute who focuses on U.S.-Israel relations and Middle East policy, told JI. “It’s one thing to have serious heterodox views. It’s another to spew dreck about Jews. Heritage is failing to draw a line in the sand.”

Among those who left the organization over their discomfort with Roberts’ decision and handling of the fallout were the leaders of an antisemitism task force that opted to sever ties with the think tank last November, even as they voiced hope to “collaborate” again.

Late last month, Luke Moon, a conservative Christian activist and co-chair of the task force, returned to Heritage as a part-time visiting fellow to support its “efforts to combat antisemitism,” the organization said in a statement.

Moon has said he chose to join the organization after Yoram Hazony, an Israeli American political theorist and national conservative leader who has denounced Carlson as antisemitic, became a member of its board in May.

But Moon said on Wednesday his recent experience had been “the opposite” of the internal culture that former staffers had described to The Times. “They’re almost a little overzealous to have me there,” he told JI. “There’s a real frustration in the reputation being tarnished.”

Still, others who left the think tank said that they remained unconvinced Roberts had meaningfully reckoned with his remarks. Yaakov Menken, the executive vice president of the Coalition for Jewish Values who resigned from the antisemitism task force last year, said that Roberts had not distanced himself from the rhetoric he used in his defense of Carlson.

“Anyone who thinks I belong to a ‘venomous coalition’ either doesn’t understand antisemitism or is a part of spreading it,” Menken told JI. “Heritage cannot combat antisemitism and endorse it at the same time.”

Josh Blackman, a legal scholar who also resigned from Heritage last year, said he had “not seen any public or private action taken by” the think tank “to adequately address” concerns over antisemitism that precipitated departures. “Until changes are made, I’m not sure how Heritage can be seen as a credible partner in the fight against antisemitism,” he told JI.

While Moon acknowledged that there were “certainly” issues at Heritage last fall, he said the think tank no longer employed problematic staffers like the former chief of staff who had written Roberts’ scripted comments about Carlson.

“There’s an explicit and very clear expectation on me to take on antisemitism on the right,” he said, adding that Heritage had also hired a researcher to help him with such work. “They’ve been very clear to me where they stand on antisemitism.”
