12 Shocking Facts About Jack Schlossberg: JFK's Grandson Who Called His Cousin A 'Rabid Dog' And Is Running For Congress

Contents

The Kennedy political dynasty is poised for a new chapter in 2025, with President John F. Kennedy’s only grandson, John Bouvier Kennedy Schlossberg, officially launching a political career that is as unconventional as it is high-stakes. Known to the public as Jack Schlossberg, the 32-year-old attorney and political commentator is blending elite academic credentials with a provocative, internet-savvy persona, making him one of the most intriguing figures in modern Democratic politics today. This article, updated in December 2025, details his background, his recent headline-grabbing political moves, and his high-profile bid for a seat in the U.S. House of Representatives.

Schlossberg’s run for Congress is the most significant political development in his life to date, but it is his recent, very public feud with his cousin, Robert F. Kennedy Jr. (RFK Jr.), that has truly cemented his status as a political provocateur. By openly and aggressively challenging members of his own famous family, Jack is signaling a break from the traditional, carefully managed image of the Kennedy clan, choosing instead a path defined by sharp rhetoric and a deliberate use of social media to engage with national issues.

The Congressional Campaign: Jack Schlossberg Enters the Fray

In a move that electrified the political world, Jack Schlossberg officially announced his candidacy for a U.S. House seat in the Democratic primary to succeed retiring Representative Jerrold Nadler. This decision marks his first formal foray into electoral politics and positions him as a significant contender for New York's 12th Congressional District.

The 12th District, which covers a significant portion of Manhattan, including the Upper West Side and parts of the Upper East Side, is a high-profile, reliably Democratic seat. Schlossberg, who is an attorney and has deep ties to the New York political scene, is leveraging both his family’s name recognition and his own unique brand of political engagement.

His campaign is being watched closely, not just because of the Kennedy name, but because of his distinct approach to politics. Unlike previous generations of Kennedys, Jack has cultivated a significant following on social media, where he frequently weighs in on national issues with a mix of earnest commentary and satirical humor. This "very online brand," as some have called it, is a deliberate strategy to connect with a younger, digitally native electorate.

Schlossberg’s platform is rooted in progressive Democratic values, focusing on issues like climate change, economic inequality, and preserving democratic institutions. He has been an outspoken supporter of Vice President Kamala Harris, demonstrating his alignment with the mainstream Democratic Party.

The RFK Jr. Feud: A Family Civil War on Social Media

Perhaps the most compelling and current storyline surrounding Jack Schlossberg is his open and often scathing criticism of his cousin, Robert F. Kennedy Jr. (RFK Jr.). RFK Jr.'s controversial political stances and his independent campaign have led to a public family rift, with Jack emerging as one of the most vocal critics within the Kennedy clan.

Schlossberg has used his platform to directly challenge his cousin’s views, particularly on public health and political rhetoric. In one of the most viral incidents, Jack publicly mocked RFK Jr. on social media with a satirical "MAHA Man" Halloween costume—a clear jab at his cousin’s anti-vaccine and conspiracy-laden rhetoric. The accompanying text referenced a lack of "medical knowledge," highlighting the deep ideological divide between the two.

Even more pointedly, upon announcing his own run for Congress, Jack Schlossberg reportedly referred to his cousin as a "rabid dog," a comment that drew immediate national headlines and a response from the White House. This level of intra-family conflict is highly unusual, even for the famously dramatic Kennedy family. Jack’s actions suggest a willingness to prioritize his political and ideological convictions over family unity, particularly when he feels the Kennedy legacy is being misrepresented or used for what he views as harmful causes.

His strategy is clear: he is positioning himself as the legitimate inheritor of the progressive, forward-thinking Kennedy mantle, in direct contrast to RFK Jr.'s populist and often conspiratorial brand of politics. By attacking his cousin, Jack is not just engaging in a family feud; he is staking a claim to the moral and political authority of the Kennedy name. This conflict is a central theme of his early campaign, helping him to generate significant media attention and distinguish himself from other candidates in the crowded New York field.

The Kennedy Legacy and Academic Excellence

Jack Schlossberg is not just a political newcomer; he is a product of one of the most intensive educational paths in American public life. His academic journey culminated in a rare and demanding joint degree from Harvard, earning both a Juris Doctor (J.D.) from the Law School and a Master of Business Administration (M.B.A.) from the Business School. Prior to his graduate studies, he earned his undergraduate degree in History from Yale University.

This dual law and business background provides Schlossberg with a unique foundation for a career in public policy and governance, blending legal expertise with a deep understanding of economic structures. His educational pedigree reflects the family's traditional emphasis on public service and intellectual rigor, setting him apart from many of his political contemporaries.

Despite his elite background, Schlossberg has often attempted to demystify his connection to the Kennedy legacy. He has spoken about the pressure of the name, but also the inspiration it provides. He is known for his work with the John F. Kennedy Library Foundation, where he has served as a voice for his grandfather's vision of service and idealism. His public appearances often draw comparisons to his grandfather, particularly for his youthful energy and confident, articulate delivery.

Schlossberg’s political trajectory is a fascinating case study of a new generation of American politicians. He is a millennial candidate who understands the power of the internet and viral content, yet he is simultaneously the direct heir to one of the most storied political families in the world. His ability to reconcile the weight of the Kennedy legacy with the demands of modern, social-media-driven politics will define his campaign for New York’s 12th Congressional District and his future in the Democratic Party.

The world is watching to see if Jack Schlossberg can successfully translate his famous name, elite education, and viral political commentary into a meaningful career in Congress, or if the burden of the Kennedy dynasty will prove too heavy, a fate that has complicated the lives of many of his relatives. For now, the "silly goose" and "social media provocateur" is officially a serious candidate, and one of the most exciting new faces in American politics.
