Jack Schlossberg revealed that his late sister, Tatiana Schlossberg, spoke her final words to him about his political ambitions.
The 33-year-old aspiring congressman told CBS Sunday Morning over the weekend that he “knows she’s still rooting for” his campaign.
“The last thing she said to me was, ‘You better win,’” Jack shared. “No one knew me better, and I knew no one better than her.”
The environmental journalist (pictured in December 2022) opened up to her brother about his congressional campaign.
Jack also reflected on growing up with Tatiana, who tragically passed away from acute myeloid leukemia in December 2025 at age 35, and their older sister, Rose Schlossberg.
“It’s brutal [to have two sisters]. Absolutely brutal,” Jack admitted. “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.”
Despite the challenges, he added, “In all honesty, they taught me everything I know about how to be a strong person.”
Jack Schlossberg (pictured in February 2017) told CBS Sunday Morning viewers that his late sister Tatiana is “still rooting” for him.
Last year, Jack, his sister Rose, their parents Caroline Kennedy and Edwin Schlossberg, Tatiana’s husband George Moran, and the couple’s two children jointly announced the environmental journalist’s passing.
“Our beautiful Tatiana passed away this morning. She will always be in our hearts,” the family wrote at the time.
Following the announcement, Jack shared several quotes from Tatiana on Instagram, starting with a passage from her 2019 book Inconspicuous Consumption:
“It’s up to us to create a country that takes seriously its obligations to the planet. Essentially, what I am describing is hard work with possibly limited success for the rest of your life. But we have to do it.”

Following her passing, Jack Schlossberg shared screenshots of poems about grief and quotes from former presidents, including their grandfather John F. Kennedy, on social media. His tribute concluded with a throwback photo of him and Tatiana standing with their hands over their hearts at an event.
The political commentator temporarily paused his campaign to succeed retiring Rep. Jerry Nadler (D-NY) in New York’s 12th Congressional District to mourn, resuming in January.
Jack’s run for Congress had begun in November 2025, the same month Tatiana publicly shared her cancer diagnosis in an emotional essay for The New Yorker.

At the time, he shared an Instagram quote: “Life is short — let it rip.”
Tatiana Schlossberg was diagnosed with acute myeloid leukemia in May 2024, shortly after giving birth to her daughter, Josephine, now 1.
She and her husband, George Moran, who married in September 2017 in Massachusetts, also welcomed a son, Edwin, in 2022.
