Maria Shriver, Meghan McCain and more shared their support for Tatiana Schlossberg after she revealed her terminal cancer diagnosis on Saturday.

“If you can only read one thing today, please make/take the time for this extraordinary piece of writing by my cousin Caroline’s extraordinary daughter Tatiana,” Shriver, a journalist and former First Lady of California, wrote in an X post on Saturday.

“Tatiana is a beautiful writer, journalist, wife, mother, daughter, sister and friend,” she continued. “This piece is about what she has been going through for the last year and a half. It’s an ode to all the doctors and nurses who toil on the frontlines of humanity. It’s so many things, but best to read it yourself, and be blown away by one woman’s life story. And let it be a reminder to be grateful for the life you are living today, right now, this very minute.”

McCain also took to social media weigh in on the news of Schlossberg’s diagnosis, calling it “devastating.”

“Absolutely devastating and heartbreaking piece,” McCain wrote in an X post. “Sending Tatiana and the entire Schlossberg/Kennedy family prayers, healing and peace in this journey. Life is so precious.”

Schlossberg’s brother Jack Schlosseberg voiced his support for his sister by sharing a link and images of her essay to his Instagram stories. In his last two story posts, he wrote: “Life is short — let it rip.”

In a weekend essay, titled “A Battle With My Blood,” for The New Yorker, the 35-year-old mother of two opened up about learning that she was diagnosed with acute myeloid leukemia, with a rare mutation called Inversion 3, after giving birth to her second child in May 2024. Aside from detailing the extensive and brutal medical journey, she slammed her cousin  Robert F. Kennedy Jr. as an “embarrassment” to their storied family.

“Throughout my treatment, he had been on the national stage: previously a Democrat, he was running for President as an Independent, but mostly as an embarrassment to me and the rest of my immediate family,” Schlossberg wrote. “Suddenly, the health-care system on which I relied felt strained, shaky. Doctors and scientists at Columbia, including [husband George Moran], didn’t know if they would be able to continue their research, or even have jobs.”

She continued: “As I spent more and more of my life under the care of doctors, nurses and researchers striving to improve the lives of others, I watched as Bobby cut nearly a half billion dollars for research into mRNA vaccines, technology that could be used against certain cancers; slashed billions in funding from the National Institutes of Health, the world’s largest sponsor of medical research; and threatened to oust the panel of medical experts charged with recommending preventive cancer screenings. Hundreds of N.I.H. grants and clinical trials were cancelled, affecting thousands of patients. I worried about funding for leukemia and bone-marrow research at Memorial Sloan Kettering. I worried about the trials that were my only shot at remission.”

Several figures in media and politics have come forward in support of Schlossberg. See their responses below.
