In a video shared on social media on Tuesday, Caroline Kennedy, the last living child of former U.S. President John F. Kennedy, referred to her cousin Robert F. Kennedy Jr.—chosen by President Donald Trump for the Secretary of Health and Human Services—as a predator.

“I have known Bobby all my life,” Caroline Kennedy states in the video while reading a letter addressed to senators. “We grew up together. It’s fitting that he keeps predatory birds as pets since he himself acts as a predator.”

There was no immediate response from the White House regarding her remarks.

Caroline’s son, Jack Schlossberg, shared the video on X, previously known as Twitter, mentioning that his mother submitted it to a Senate committee, a detail first reported by the Washington Post. The confirmation hearing for RFK Jr. is slated for Wednesday at 10 a.m.

In her letter, she acknowledged her cousin’s recovery from substance abuse but criticized him for encouraging family members to engage in drug use before he got sober, leading to addiction, illness, or death among them. She further accused him of having a history of “misrepresenting, lying, and cheating” throughout his life.

“Bobby craves attention and power,” Caroline Kennedy remarked in the video. “He exploits the desperation of parents with sick children—vaccinating his own kids while hypocritically advising other parents against vaccinating theirs.”

She described the role of overseeing the Department of Health and Human Services—responsible for the FDA and NIH—as a “huge responsibility, one that Bobby is not fit to handle.”

“He lacks significant experience in government, finance, management, or medicine,” Caroline Kennedy continued. “His opinions on vaccines are dangerous and intentionally misinformed. The facts alone should disqualify him, but his personal traits connected to this job raise even more serious concerns for me.”

RFK Jr. has admitted to past issues, describing himself as “not a church boy.” A former babysitter, who is about two decades younger than him, accused him of sexual assault. He publicly apologized to her but claimed he doesn’t remember the incident. The matter was never brought to court.

In December, a group of seventy-seven Nobel Prize winners expressed their opposition to his confirmation, warning that his leadership could “endanger public health.”
