Jacob Reses, the Jewish chief of staff to Vice President JD Vance, is leaving the administration at the end of the summer, a source confirmed to the Jewish Telegraphic Agency on Thursday.

Reses, who’s been in his role since Vance and President Donald Trump took office in January 2025, is perhaps the closest Jewish official in Vance’s orbit. He has had a close relationship with the vice president since Vance’s 2022 Senate campaign in Ohio.

A source familiar with the matter confirmed NBC News’ initial report that Reses informed Vance of his decision months ago, after his wife became pregnant. Vance said in a statement on Thursday that he will “miss him dearly, but he won’t be far, and I plan to keep his counsel close until our paths cross again.” Reses’ plans for his next role are currently unknown.

Vance has recently drawn the ire of some Jewish Republicans who say that he has refused to confront antisemitism on the right, including from former Fox news host Tucker Carlson. (Carlson’s son is also a Vance staffer.) A New York Magazine profile published in March suggested that Reses was on board with Vance’s approach, and revealed that Reses used his private X account to amplify voices calling on Jews to embrace, rather than resist, the Christian nationalist current surging within the GOP.

Reses has been “by my side for my whole career in public life,” Vance said in a statement.

“I can’t imagine having been on this life-changing journey without him,” Vance said. “From day one of my time as a Senator-elect, I could not have asked for a more loyal and discerning advisor and friend as my chief of staff.”

The personal bond between the two men was on display in January, when Vance took part in Reses’ wedding to Rachel Altman at a synagogue in Rockville, Maryland, delivering a Jewish prayer under the chuppah. Chabad of Princeton University, Reses’ alma mater, posted a photo of the couple with the vice president, celebrating the occasion as an expression of Jewish pride.

That closeness, and Reses’ reported alignment with Vance’s stance on right-wing antisemitism, have not spared Reses from becoming a target of antisemites. In one instance, a white-nationalist website ran an article about him headlined, “Another Nail in the Coffin — Jew Runs J. D. Vance.”

A Jewish Telegraphic Agency profile published in 2024, when Vance was selected as Trump’s running mate, traced Reses’ Jewish identity and his journey from a Democratic-leaning Jewish teenager in southern New Jersey, whose grandfather escaped the Holocaust in Lithuania, to one of the most influential conservatives in Washington. His trajectory included internships for Hillary Clinton and John Kerry, a political conversion at Princeton and stints at the Heritage Foundation and in the office of Missouri Sen. Josh Hawley.

On Thursday, Republican leaders and Trump administration officials sang Reses’ praises in statements shared with JTA.

“Jacob Reses has been an invaluable, loyal, and trusted hand to Vice President Vance and President Trump,” said Matt Brooks, CEO of the Republican Jewish Coalition. “As a proud Jewish American, whose own family story carries the weight of our people’s history, Jacob brought both conviction and clarity to one of the most consequential roles in Washington.” Brooks added that the RJC has “no doubt he will continue to play a critical role moving forward.”

Secretary of State Marco Rubio, who’s seen as a possible challenger to Vance for the 2028 presidential nomination, said that Reses served Vance and the entire administration “with distinction,” and that he “understands the moment we’re in and he spent every day fighting to deliver results for the President.”

Steve Witkoff, Trump’s special envoy to the Middle East, said he was proud to have Reses “by my side in negotiating some of the toughest deals for the President.”

“Don’t let Jacob fool you — beneath his kind exterior he’s a killer,” Witkoff said. “It’s been a delight to get to know him through the Vice President, and our foreign adventures from Israel to Pakistan have been historic.”

He added, “We haven’t seen the last of him.”
