Jack Schlossberg remembers the last words from his sister, Tatiana. Late last year, the Kennedy family was dealt a harsh blow, with Tatiana Schlossberg, Jack’s sister and the daughter of Caroline Kennedy, dying of cancer at the age of 35.
Schlossberg, 33, recently made an appearance on CBS News Sunday Morning, discussing his campaign for New York’s 12th Congressional District in the U.S. House of Representatives.
He revealed that his sister shared his support for his mission before her death. “I can tell you now that she’s still rooting for us,” he said, when discussing his campaign and Tatiana.
“The last thing that she said to me was, ‘You better win,’” he continued. “No one knew me better, and I knew no one better than her.” Schlossberg paused his campaign for two weeks following his sister’s death.

“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.”

“I did not — could not — believe that they were talking about me,” she wrote. “I had swum a mile in the pool the day before, nine months pregnant. I wasn’t sick. I didn’t feel sick. I was actually one of the healthiest people I knew.” She was married to George Moran in 2017, with the two sharing two kids: a son, 3, and a daughter, 1.
Tatiana was a Yale and Oxford graduate, building a career in environmental journalism, discussing topics like climate change and ocean conservation. She published a book titled “Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have,” and a newsletter published on The New York Times titled “News from a Changing Planet.”
Following her death, tributes poured in from family and friends, including his cousin Maria Shriver, who described Tatiana as “a beautiful writer, journalist, wife, mother, daughter, sister, and friend.”
