Jack Schlossberg revealed that his late sister Tatiana Schlossberg’s last words to him were about his campaign.
The 33-year-old House candidate told “CBS Sunday Morning” viewers over the weekend that “I know she’s still rooting for me” in his political career.
“The last thing she said to me was, ‘You better win,'” Jack revealed on Sunday. “No one knew me better than she did, and no one knew me better than she did.”
He also reflected on growing up with Tatiana and her sister Rose Schlossberg, who lost her battle with acute myeloid leukemia in December 2025 at age 35.
“It’s cruel (having two sisters). It’s really cruel,” Jack said. “They won’t let me do anything. My style is never good enough. I’ve never had the right answer in my life.”
However, he admitted, “Honestly, they taught me everything about how to be a strong person.”
Jack and Rose, along with his parents Caroline Kennedy and Edwin Schlossberg, Tatiana’s husband George Moran, and the couple’s two children signed a statement announcing the environmental journalist’s death last year.
“Our beautiful Tatiana passed away this morning. She will always be in our hearts,” they wrote at the time.
Jack then shared various quotes on Instagram, starting with a passage from Tatiana’s book “Inconspicuous Consumption,” published in 2019.
“It’s up to us to build a nation that takes its obligations to the planet seriously,” it read. “Essentially, what I’m describing is hard work with potentially limited success for the rest of our lives. But we have to do it.”
Jack posted screenshots of poems about grief and quotes from former presidents, including his grandfather, John F. Kennedy.
The social media tribute had no caption, but ended with a throwback snap of Jack and Tatiana standing with their hands on their hearts at the event.
Out of sadness, the political commentator paused his campaign to replace retiring Rep. Jerry Nadler (D-N.Y.) in New York’s 12th Congressional District, then resumed it in January.
His bid for Congress began in November 2025, the same month Tatiana announced the news of her cancer in an emotional essay for The New Yorker.
Jack responded on Instagram at the time with the comment, “Life is short, try your best.”
Tatiana was diagnosed with the disease in May 2024, shortly after giving birth to her daughter Josephine, who is now one year old.
She and Moran, who married in Massachusetts in September 2017, welcomed a son, Edwin, in 2022.
