Tatiana Schlossberg, an environmental journalist and the granddaughter of President John F. Kennedy, has announced that she has been diagnosed with terminal cancer. The revelation came in a personal statement where she also issued a sharp rebuke against her cousin, Robert F. Kennedy Jr., for what she described as his role in promoting dangerous misinformation.
In her announcement, Schlossberg, 35, reflected on her diagnosis, stating that facing her own mortality has sharpened her perspective on the importance of scientific integrity and public health. An author known for her work on climate change, she drew a direct line from her personal health battle to the broader societal risks posed by the rejection of scientific consensus. She accused her cousin of contributing to a culture of distrust that has "lethal consequences," a sentiment made more poignant by her own prognosis.
Schlossberg’s criticism is the latest instance of a deep and public rift within the Kennedy dynasty over RFK Jr.’s political career and his controversial views. She joins several other family members, including her brother Jack Schlossberg, in openly opposing him. Last year, many Kennedys publicly endorsed President Joe Biden over their own relative, a move that highlighted the family's stark political divisions.
Details of Schlossberg’s specific diagnosis were not made public. Her statement focused primarily on channeling her personal struggle into a call for greater respect for science and medicine. According to reports from Sky News covering the announcement, her message underscores a profound disagreement with RFK Jr.'s long-standing skepticism toward vaccines and established medical science. This public denouncement from a family member facing a terminal illness adds a deeply personal and tragic dimension to the ongoing political debate surrounding RFK Jr.'s platform and his impact on public discourse.
