The Heritage Foundation is facing a staff rebellion over its president, Kevin Roberts, expressing support of Tucker Carlson following his softball interview with neo-Nazi Nick Fuentes.

After Carlson posted his interview online on Monday, many conservatives urged the foundation to distance itself from the conservative commentator due to Fuentes’s racist and antisemitic views. Fuentes is the founder of the Groypers, a group of internet trolls that praises Hitler as well as white and Christian nationalism.

Instead, Roberts released a video on X Thursday in support of Carlson and Fuentes, calling the former “a close friend of the Heritage Foundation” and saying that “canceling” Fuentes is not the solution, even though he personally abhors what he says. In response, Heritage staff members—including Heritage research fellow Preston Brashers and Richard Stern, the director of Heritage’s economic policy institute and federal budget center—have started criticizing Roberts on social media.

At least a handful of Heritage staffers, including Jason Bedrick, Jay Greene, and John Peluso, also retweeted Brashers’s post. Other conservatives, including Senator Ted Cruz and influencer Bethany Mandel, have also criticized Roberts. The backlash led to Roberts making a follow-up post on Friday condemning Fuentes’s views but reiterating his view “that the best way to fight antisemitic ideas was to challenge them head on.”
