JFK’s grandson Jack Schlossberg shares sister Tatiana’s last words to him
Jack Schlossberg has revealed his late sister Tatiana’s last words to him before her death in December last year.
The grandson of the late John F. Kennedy recalled that, weeks after announcing her terminal cancer diagnosis, his sister talked to him about his aspirations for a political career.
“The last thing that she said to me was, ‘You better win,’” Jack said during Sunday’s episode of CBS Sunday Morning, referencing his run for Congress in New York’s 12th District. “No one knew me better, and I knew no one better than her.”
Jack also spoke about what it was like to grow up along Tatiana and his older sister, Rose Schlossberg.
“It’s brutal [to have two sisters]. Absolutely brutal,” he said. “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.”
However, he added that being the family’s only son did come with some blessings, saying, “In all honesty, they taught me everything I know about how to be a strong person.”
The JFK Library Foundation announced Tatiana’s death in a statement in December 2025. “Our beautiful Tatiana passed away this morning. She will always be in our hearts,” the statement read. It was signed “George, Edwin and Josephine Moran, Ed, Caroline, Jack, Rose and Rory.”
She was survived by her husband, George Moran, their three-year-old son, and their one-year-old daughter. She’s also survived by her parents, Caroline Kennedy and Edwin Schlossberg, and her siblings Jack, and Rose Schlossberg, who is married to Rory McAuliffe.
Tatiana revealed she had been diagnosed with a rare type of acute myeloid leukemia, a blood cancer, in a New Yorker essay published on November 22, 2025, the 62nd anniversary of her grandfather’s assassination.
In the essay, she recounted her disbelief in her diagnosis, as the disease is mostly seen in older people.
“I did not — could not — believe that they were talking about me. I had swum a mile in the pool the day before, nine months pregnant. I wasn’t sick. I didn’t feel sick,” she wrote.
She was diagnosed shortly after giving birth to her daughter in May 2024. Her doctors noticed her white blood cell count was elevated just hours after she delivered her daughter.
“Everyone thought it was something to do with the pregnancy or the delivery. After a few hours, my doctors thought it was leukemia,” she wrote.
She recalled feeling worried that her young children would not remember her after her death.
“During the latest clinical trial, my doctor told me that he could keep me alive for a year, maybe. My first thought was that my kids, whose faces live permanently on the inside of my eyelids, wouldn’t remember me,” Tatiana wrote.
