Tatiana died at 35 on Dec. 30, about a month after publicly sharing that she had been diagnosed with acute myeloid leukemia

Jack Schlossberg has revealed the last thing his older sister, Tatiana Schlossberg, told him before her death.

The 33-year-old grandson of former President John F. Kennedy and Jackie Kennedy Onassis said in an interview with CBS News Sunday Morning on March 1 that his sister’s last words to him were in support of his campaign to represent New York’s 12th Congressional District in the U.S. House of Representatives.

When Jack was asked what his late sister thought about his candidacy, he said, “I can tell you now that she’s still rooting for us.”

“The last thing that she said to me was, ‘You better win,’ ” Jack continued. “No one knew me better, and I knew no one better than her.”

Tatiana died at 35 on Dec. 30, about a month after publicly sharing her acute myeloid leukemia diagnosis.

The news of Tatiana’s death was shared by the JFK Library Foundation.

“Our beautiful Tatiana passed away this morning. She will always be in our hearts,” read the Instagram post, which was signed by “George, Edwin and Josephine Moran, Ed, Caroline, Jack, Rose and Rory.”

In addition to Jack and Tatiana, Edwin Schlossberg and Caroline Kennedy also share daughter Rose Schlossberg.

Jack spoke about his experience growing up with two sisters, telling CBS News Sunday Morning, “It’s brutal. Absolutely brutal. They don’t let you get away with anything. My style is never good enough. I’ve never gotten an answer right in my entire life. But in all honesty, they taught me everything I know about how to be a strong person.”

Tatiana had two children — son Edwin, born in 2022, and daughter Josephine, born in 2024 — with husband George Moran.

As for being an uncle, Jack called himself “the best one.”

“We’re a really close family. For me, when you talk about the Kennedy family, it’s a lot of people I don’t know. When you talk about what family is, it’s me, my sisters, my parents. We’re a unit and we’re really close,” he said.

Jack resumed his congressional campaign two weeks after Tatiana’s death, echoing one of her messages.

The Democrat supported a rally for the New York State Nurses Association on Jan. 12, during which he said, “Nurses should rule the world, if you ask me. Nothing is more important than supporting our nurses.”

 

 

Tatiana publicly shared that she had been diagnosed with acute myeloid leukemia in a deeply personal essay published in November by The New Yorker. In the essay, she proclaimed that “nurses should take over.”

On Jan. 5, days after her Dec. 30 death, Jack shared a powerful piece of writing from Tatiana in an Instagram post that also contained 10 quotes from well-known writers and public figures. The final slide showed him standing beside Tatiana with their hands over their hearts at the U.S. Capitol.
