Caroline Kennedy is “living in fear” that her controversial son Jack Schlossberg’s run for Congress could make him “a target for violent haters,” sources told The Post.
Schlossberg — a progressive Democrat with a combined following of around 1.6 million on social media, where he’s earned a reputation for his bizarre rants — on Tuesday announced a run for the Manhattan congressional seat held for more than three decades by retiring “liberal lion” Jerrold Nadler, 78.
“Caroline has pleaded with Jack not to run, but he seems determined to follow in the political footsteps of his grandfather [President John F. Kennedy] and generations of other Kennedys who have held political office,” one insider reveals.
“Jack’s decision to throw his hat in the ring has seriously frightened Caroline, who believes the political world has become too dangerous, too frightening, too crazy, and so she doesn’t want her only son … running for elective office in the current toxic environment,” a close source told The Post.
The Post has reached out to Kennedy.
Nadler announced in September that he would be stepping aside as it is “the right time to pass the torch to a new generation.”
“Each generation of Americans is tested. The 2026 midterms is our moment,” Schlossberg’s website for his 12th district run reads. “I’m running for Congress because the best part of the greatest city on earth needs to be heard loud and clear in Washington and deserves a representative who won’t back down.”
So far, three other candidates have officially joined the Democratic primary race: Alex Bores, a former software engineer who has represented Manhattan’s 73rd District in the State Assembly since 2023; state lawmaker Micah Lasher, a Nadler protege; and Liam Elkind, founder of the nonprofit group Invisible Hands.
Although there were reports that Schlossberg could go up against another Dem scion, Chelsea Clinton, her team has denied she will run.
In August, Sen. Chuck Schumer gave Schlossberg, 32, a seal of approval of sorts when the US Senate Minority Leader appointed the Kennedy scion to the committee prepping America’s 250th birthday bash.
“Why am I putting Jack there? We know that Donald Trump will try to aggrandize the whole thing and make it part of him and his ego,” Schumer said in a social media video appearance alongside Schlossberg. “There’s no better person to push back on that than you, Jack.”
Schlossberg has certainly pushed buttons on social media. Besides oddly joking that Second Lady Usha Vance was going to be the mother of his child, he asked followers who was hotter — Vance or his late grandmother Jacqueline Kennedy Onassis.
“I’m a literal pervert. I called my grandmother hot… have I totally lost it ? Jesus … this kid will do anything for attention. Your grandfather would be ashamed. Seriously. Time to get a job” he posted on X in January.
A frequent critic of his cousin Robert F. Kennedy Jr. (as are many members of their family), he has mocked the Secretary of Health and Human Services’ spasmodic voice disorder and posted a fake RFK Jr. “MAHA Man” Halloween costume — with packaging that said “Includes sexual assault.”
“I have never met Cheryl Hines but if I did, I’d tell her she looks super-dehydrated,” he said on X late last month of RFK Jr.’s actress wife.
In February, RFK Jr.’s daughter Kick Kennedy — Schlossberg’s second cousin — told The Post of Schlossberg, “I hope he gets the help he needs.”
Another worry “weighing heavily on Caroline” regarding Schlossberg’s political run, according to a family source, is the resurgence of antisemitism in America -—and how that kind of hate could impact her son as a candidate.
Caroline’s husband Edwin Schlossberg is Jewish though the two wed in a Catholic church wedding in 1986.
In one of his snarky postings on Instagram, Schlossberg once compared his physical characteristics to his dad’s, sarcastically declaring, “I am my father’s Schnoz,” and suggested that his famous Kennedy ancestry is overplayed.
Jerry Oppenheimer is the author of “The Other Mrs. Kennedy,” a biography of Ethel Kennedy, and “RFK Jr. And The Dark Side of the Dream.”
