Jack Schlossberg — John F. Kennedy‘s only grandson — is looking to carry on his famous family’s political legacy … announcing a bid for Congress.

The 32-year-old Democrat posted a video on social media Tuesday night revealing he’s running for New York’s 12th congressional district — the seat long held by Rep. Jerry Nadler, who’s retiring after 34 years in office.

Check out the clip … Schlossberg is seen buttoned up and speaks directly to the camera — warning America is facing a “crisis at every level,” and saying, “we can do better” by having the Democrats take back control of the House.

Schlossberg also has a massive online following — roughly 1.6 million followers across his social platforms — where he’s known for taking unapologetic swings at Republicans … and at times, going on eyebrow-raising rants.

Caroline Kennedy’s son joined us on “TMZ Live” in August … where he doubled down on a video taunting Melania Trump — after she wrote a letter to Vladimir Putin asking him to protect children caught up in the Ukraine war.

Schlossberg will definitely grab attention … and things could get heated fast in what may become a crowded primary in one of the wealthiest districts in the country.
