Jack Schlossberg told viewers of "CBS Sunday Morning" over the weekend that the final words his late sister Tatiana ever spoke to him were about his campaign for Congress.
The last thing that she said to me was, 'You better win.'
The 33-year-old aspiring congressman, who is running to replace retiring Rep. Jerry Nadler in New York's 12th Congressional District, opened up about Tatiana, the family he grew up in, and the grief that interrupted his political debut before it had barely begun.
Tatiana Schlossberg lost her battle with acute myeloid leukemia in December 2025 at the age of 35. She was diagnosed in May 2024, immediately after giving birth to her daughter Josephine. She went public with the diagnosis in an emotional essay in The New Yorker that same November, the very month Jack launched his congressional bid.
The family released a statement signed by Jack, their older sister Rose, their parents Caroline Kennedy and Edwin Schlossberg, Tatiana's husband George Moran, and the couple's two children.
Our beautiful Tatiana passed away this morning. She will always be in our hearts.
According to Page Six, Jack paused his campaign to grieve, resuming in January. The timeline is worth sitting with. He announced a run for Congress. His sister told the world she had cancer. She died weeks later. He buried her, then got back to work. Whatever you think of his politics, that sequence demands something heavier than a shrug.
Schlossberg reflected on what it was like growing up with Tatiana and their older sister Rose, and he did it with the kind of self-deprecating honesty that rarely survives the polish of a campaign.
It's brutal [to have two sisters]. Absolutely brutal.
He said they never let him get away with anything, that his style was "never good enough," and that he had "never gotten an answer right" in his entire life. Then he turned serious.
In all honesty, they taught me everything I know about how to be a strong person.
Of Tatiana specifically, he said no one knew him better, and he knew no one better than her. He told CBS viewers he knows she is still rooting for his political career.
Tatiana Schlossberg was an environmental journalist and the author of "Inconspicuous Consumption," published in 2019. She married George Moran in September 2017 in Massachusetts, and together they had two children: a son, Edwin, born in 2022, and a daughter, Josephine, now 1.
In the wake of her death, Jack took to Instagram to share quotes from her book, poems about grief, and words from former presidents, including their grandfather John F. Kennedy. One quote he highlighted captured the restless energy of someone refusing to waste time: "Life is short — let it rip."
There is something clarifying about watching a young candidate process grief in real time. Campaigns are built to manufacture urgency. Every fundraising email screams that the republic hangs by a thread. But a sister dying of leukemia at 35, weeks after you file to run for office, is an actual urgency. It strips the veneer off everything else.
Schlossberg is a Democrat running in one of the bluest districts in the country, the grandson of a president whose name still carries weight in American politics. Conservatives will find plenty to disagree with him about. That is what elections are for.
But grief does not belong to a party. A 33-year-old man lost his sister, stepped away, came back, and told the country her last words were a command to win. Whether he does or not, that is not a campaign line. That is a wound wearing a suit.
Tatiana Schlossberg was 35. She left behind two children, a husband, a family accustomed to public tragedy, and a brother who now carries her final instruction into a race she will never see the end of.
