LAS VEGAS — Vice President JD Vance has faced skepticism from some in the Jewish Republican community. He waded directly into the fray Monday — and was met with raucous applause.In a closed-door appearance at the Republican Jewish Coalition leadership summit, Vance addressed what he called the “elephant in the room”: Israel’s plummeting favorability among young Americans, according to one people in the room for Vance’s speech, granted anonymity to describe an off-record conversation, and audio of the event obtained by POLITICO. Vance also discussed rising antisemitism.“There is a growing suspicion among, I would call it, under-40s of the U.S.-Israel relationship,” Vance said in a moderated conversation with former Sen. Norm Coleman (R-Minn.), chair of the RJC board. “I think my view is, what we have to do is articulate why this is in the best interest of the United States of America, and actually get out there and talk about the ways in which it is in the best interest of the United States of America.”Vance noted that Republicans must “talk about the concrete alignment of interest and to hook a relationship on that, rather than something that may have made a lot of sense rhetorically 30 or 40 years ago, but just doesn’t have … the same purchase as it did 30 or 40 years ago because the country is different and because young people are looking at this in a different way.”Vance’s appearance at the annual RJC confab — hosted at the Venetian Resort, developed by the late GOP megadonor Sheldon Adelson — came as a surprise to many in the pro-Israel community, with which Vance has shared a sometimes tumultuous relationship. Vance, the current frontrunner for the Republican presidential nomination in 2028, will likely need to shore up support from the community to succeed Trump.The hesitancy toward Vance among some in pro-Israel circles boiled up in recent months over Vance’s dovishness on the Iran war and his criticism of Prime Minister Benjamin Netanyahu’s Israeli government. But other concerns go back further, centered on his longtime relationship with Israel-skeptical pundit Tucker Carlson and the way he’s addressed antisemitic incidents or statements.Some pro-Israel megadonors, like billionaire hedge fund manager Ken Griffin, have already signaled they’d support Secretary of State Marco Rubio in 2028 over Vance. (Neither Vance nor Rubio have announced whether they’ll seek the presidential nomination, though Rubio has stated he will not run if Vance does.)But Vance’s speech was met with applause inside the cavernous convention hall where it was delivered, and praise outside of it.“He hit a home run with the crowd,” Sen. Jim Banks (R-Ind.) told reporters after the speech, noting Vance received “several standing ovations.”The Jewish community has “a great ‘bullshit detector,’ to understand when they’re being pandered to,” said Matt Brooks, CEO of the RJC. “And I don’t believe that anybody will come away from this meeting thinking that they were pandered to. I think they will come away from this conversation with a sense that the vice president really gets it and gets us.”Last year, the RJC’s leadership summit was centered on combatting antisemitism within the Republican Party, and leaders took aim at Carlson and others. Vance has been an ally of Carlson’s, and when Coleman asked Vance about podcasters like Carlson, Vance gave a winding answer.“I recognize a lot of people in this room may disagree with things that Tucker Carlson or Megyn Kelly or Joe Rogan have said,” Vance said, before focusing on Rogan and Fuentes, saying they are “two very, very different categories of people.””I think it’s a mistake to sort of say we’re going to write Joe Rogan off because he said something that we don’t like,” he said. “I think the best approach is to actually go in there and talk to him and make the argument as best as you can.”Vance directly condemned some antisemitic theories like blood libel, saying it is the exact opposite of the Christian gospel. He said that Jew-hatred is “corrosive to the soul.”And echoing other speakers at the two-day RJC summit, Vance declared that former Rep. Mike Rogers (R-Mich.) is the most important Senate candidate this cycle, and urged those in attendance to support him in his race against Democratic nominee Abdul El-Sayed.Earlier Monday, Vance rallied alongside Rogers at a Michigan event hosted by MAGA Inc., Trump’s super PAC, before flying to Nevada. His cross-country itinerary signaled his seriousness in courting the Jewish donor community, suggested Robert Schostak, an RJC board member.“I think it’s great that he’s here. This is not easy,” said Schostak, the former Michigan GOP chair. “He cares about the fight of antisemitism, and the support for Israel. If this was secondary to him, he wouldn’t be here.”Ari Fleischer, an RJC board member and a former White House press secretary, agreed. “Today is not primary day,” he said. “But I think today was progress day for JD Vance with the Jewish community.”
