Jack Schlossberg Shows Support After Sister Tatiana Reveals Terminal Cancer Diagnosis Days into His Congressional Campaign

Not long after Tatiana Schlossberg publicly shared that she is living with terminal cancer, her brother Jack Schlossberg posted a quiet but pointed show of support.

In an essay published in The New Yorker on Saturday, Nov. 22, Tatiana, 35, wrote that she was diagnosed with acute myeloid leukemia soon after giving birth to her second child in May 2024. She explained that after several rounds of treatment, her doctor recently told her she likely has about a year to live.

Within hours of the essay’s release, Jack, 32, shared screenshots from it on Instagram Stories, including the title, “A Battle with My Blood,” and the opening paragraph, along with a link to the piece. He later added his own brief message over two separate images—one appearing to show a road and another the sky—writing, “Life is short — let it rip.”

Jack’s posts came just days after he announced a congressional run. Following the retirement news of longtime New York Rep. Jerry Nadler, he launched his campaign through a Nov. 11 email to supporters and an interview with The New York Times.

In her essay, Tatiana mentioned both Jack and their older sister Rose Schlossberg, 37, while describing the family’s support during her illness. Tatiana, who shares a 3-year-old son and a 1-year-old daughter with her husband, George Moran, thanked him for how he has carried the practical burdens of treatment and hospitalization.

She also reflected on her parents, brother, and sister stepping in to help care for her children and to be present through the hardest stretches of her medical journey. Tatiana wrote that their steady presence has been a profound gift, even as she feels their grief alongside her own.

Later in the essay, she turned to the weight her diagnosis places on her mother, Caroline Kennedy. Tatiana noted that she has spent her life trying to protect her mother from pain, and now feels she has added another tragedy to a family already shaped by loss.
