Jack Schlossberg, the 32-year-old grandson of former President John F. Kennedy, announced Tuesday night that he will run for Congress in New York’s 12th Congressional District in 2026, setting up a closely watched campaign that revives one of America’s most famous political legacies.

The seat is currently held by Rep. Jerry Nadler, who revealed in September that he will not seek reelection after more than three decades in Congress.

In a video posted to Instagram, Schlossberg — whose full name is John Bouvier Kennedy Schlossberg — framed his campaign as a fight for economic fairness and against what he described as the damaging policies of President Donald Trump and the Republican-controlled Congress.

“We deserve better, and we can do better — and it starts with the Democratic Party winning back control of the House of Representatives,” Schlossberg said.

He criticized Trump’s so-called “Big Beautiful Bill,” the administration’s flagship economic package, which he claimed had triggered a “cost of living crisis” and “historic cuts to the social programs working families rely on — health care, education, child care.”

“With control of Congress, there’s nothing we can’t do. Without it, we’re helpless to a third term,” Schlossberg added, in an apparent reference to Trump’s continued political dominance.

The president, who has previously declined to rule out seeking a third term despite constitutional limits, appeared to acknowledge in late October that he could not legally do so.

Schlossberg, the only grandson of JFK and Jacqueline Kennedy Onassis, graduated from Yale University and Harvard Law and Business Schools. He has long been seen as a potential political contender, occasionally representing the Kennedy family at public events and Democratic Party gatherings.

In a press release announcing his candidacy, Schlossberg emphasized his commitment to the Democratic Party, noting that he has “spoken across the country as a surrogate for President Joe Biden and Vice President Kamala Harris,” including at the most recent Democratic National Convention.

If elected, Schlossberg would become the first member of the Kennedy family to serve in Congress since his cousin, former Rep. Joe Kennedy III, left office in 2021.

His entry into the race immediately injects national attention — and a touch of Camelot nostalgia — into what could become one of the most high-profile Democratic primaries of the 2026 election cycle.
