Republican vice presidential candidate Senator JD Vance will join political commentator and former Fox News host Tucker Carlson at the Giant Center in Hershey on September 21 as part of Carlson’s first “live tour.”

Vance, who said he will be in Pennsylvania “a lot” before Election Day, will appear as a special guest on Carlson’s show. Carlson recently came under fire for inviting Holocaust revisionist Darryl Cooper onto his show on X on Monday.

A spokesman for Vance declined to comment on the situation. The planned appearance comes as Republicans seek, without evidence, to portray Vice President Kamala Harris as an anti-Semite and just weeks after former President Donald Trump said Harris did not choose Pennsylvania Governor Josh Shapiro as her running mate because he is Jewish.

During a two-hour conversation with Carlson, Cooper said British Prime Minister Winston Churchill was the “main villain” of World War II. Churchill assembled and led a coalition to defeat Adolf Hitler’s Nazi Germany in the war.

Cooper added that Hitler “did not want to fight” and was “largely responsible” for the outbreak of war in 1941 in which the Germans “were not prepared to deal with the millions and millions of prisoners of war, local political prisoners, etc. that they had to deal with.”

Carlson, who described himself as a “supporter” of Cooper’s work, did not contradict these comments and called on Cooper to defend his stance against Churchill.

Cooper’s appearance on Carlson’s show sparked a fierce reaction online. Former U.S. Representative Liz Cheney (R-Wyoming), a fierce Trump critic, called Cooper’s comments “pro-Nazi propaganda,” adding, “No serious or honorable person would support or condone this nonsense.”

This is not the first time Carlson has used dangerous rhetoric, including promoting narratives consistent with the Great Replacement Theory, a baseless, racist theory that claims there is a conspiracy to “reduce white influence.”

Vance has been the central figure in many of his own controversies, including when he spoke of the government being run by “a bunch of childless cat ladies” in a 2021 interview with Carlson. Vance has also exchanged text messages with Charles Johnson, a far-right media personality and Holocaust denier, the Washington Post reported.

“Chuck Johnson was sending spam text messages to JD Vance,” William Martin, a spokesman for Vance, told Politico in early August. “JD usually ignored him but occasionally responded to push back against things he had said.”

Carlson’s “Live Tour” features “some of the most fascinating and well-known guests reacting in real time to everything that happens,” the event page says. Tickets are sold on Ticketmaster for up to $125.

Although not an official Trump campaign event, Vance’s appearance with Carlson marks his fifth scheduled stop in Pennsylvania since being nominated as vice presidential candidate.

“All of you in Pennsylvania are going to get sick of me in the next two months because I practically live here in the state of Pennsylvania because this state is so important to us,” Vance said at a campaign event in Erie on August 28.
