Tatiana Schlossberg, a 35-year-old member of the Kennedy family, has disclosed a terminal acute myeloid leukemia diagnosis and used a New Yorker essay to criticize her cousin, Robert F. Kennedy Jr., now the HHS secretary.

Tatiana Schlossberg announced a devastating medical diagnosis in an essay published in The New Yorker and discussed the personal fallout that followed. She is 35, the granddaughter of former President John F. Kennedy, the daughter of Caroline Kennedy and Edwin Schlossberg, and the second cousin of Robert F. Kennedy, Jr., the current Health and Human Services (HHS) secretary. Her piece blends intimate family detail with pointed political frustration.

Her diagnosis is acute myeloid leukemia with a rare mutation, and she says multiple treatments have failed since the illness was identified in May 2024. Doctors discovered the cancer on May 25 when routine bloodwork showed a striking spike in white cells. The scale of that spike was reported as a white cell count had spiked to 131,000 cells per microlitre, more than 10 times normal levels.

Tatiana Schlossberg, 35, disclosed her terminal diagnosis in a Saturday essay in The New Yorker, writing that acute myeloid leukemia with a rare mutation has resisted multiple treatments since May 2024. Doctors found the cancer on May 25 when blood tests showed her white cell count had spiked to 131,000 cells per microlitre, more than 10 times normal levels.

The diagnosis arrived at an especially painful moment for Schlossberg, because it followed the birth of her child by only hours. Reporters note the diagnosis came “just hours after Schlossberg delivered her daughter at Columbia-Presbyterian Hospital in New York.” That timing deepened the shock and personal stakes around her prognosis and treatment options.

Her first instinct after learning the news was not political, but maternal. She said her immediate worry was about how her children would remember her and hold onto her presence in their lives. That fear appears to be a central emotional thread in the essay.

My first thought was that my kids, whose faces live permanently on the inside of my eyelids, wouldn’t remember me. My son might have a few memories, but he’ll probably start confusing them with pictures he sees or stories he hears.

Even while undergoing intense therapy, Schlossberg directed sharp criticism at her cousin, Robert F. Kennedy, Jr., for his confirmation to head HHS. From her hospital bed she says she watched in horror as his appointment moved forward and felt the system she depended on grow uncertain. She describes growing worry about access to specialized trials and care during a moment of transition in federal health leadership.

Tatiana Schlossberg, 35, said she watched in horror from her hospital bed as RFK Jr was confirmed for the top health post in February. She said the health-care system she relied on suddenly felt ‘strained, shaky’ after RFK Jr’s confirmation and that she worried about losing access to leukemia and bone-marrow trials at Memorial Sloan Kettering, her best chance at remission.

Her anger did not stop with concern about access to trials; she leveled a personal rebuke as well. Schlossberg wrote that RFK Jr was “mostly an embarrassment to me and the rest of my immediate family” while she underwent treatment that included CAR-T therapy. Those words underscore how family loyalty and political choices collided in a moment of private crisis.

In the same piece, she launched a scathing attack on her second cousin, RFK Jr, over his appointment as Secretary of Health and Human Services. Schlossberg wrote that RFK Jr was ‘mostly an embarrassment to me and the rest of my immediate family’ as she underwent CAR-T therapy, a treatment developed through decades of government-funded research.

From a Republican perspective, the episode highlights two competing realities: a tragic personal health battle and a broader political debate over who should lead national health policy. Conservatives have generally supported changes that challenge entrenched interests in health care, and RFK Jr.’s selection has been defended as part of that shake-up. Still, family criticism like this makes for difficult optics for any administration trying to show steady leadership.

Schlossberg’s essay raises hard questions about treatment access, the role of federal research in breakthrough therapies, and how public appointments affect private lives. The Kennedy family has long been a political barometer, and this disagreement adds another chapter to their complex public story. RFK Jr. has been seeing a lot of this from his family ever since he teamed up with President Donald Trump.
