How is RFK Jr. related to John F. Kennedy?

Family tree overview

• RFK Jr. is the son of Robert F. Kennedy (U.S. Attorney General) and Ethel Kennedy (HHS.gov (official agency biography)).
• Robert F. Kennedy was President John F. Kennedy’s younger brother.
• Thus, John F. Kennedy is RFK Jr.’s uncle.
• RFK Jr. was born in Washington, D.C., on January 17, 1954 (HHS.gov).

RFK Jr.’s parents and siblings

• He is the third of 11 children in the Robert and Ethel Kennedy family (Britannica (established reference work)).
• He was nine years old when President John F. Kennedy was assassinated in 1963 (Miller Center at the University of Virginia (presidential history research center)).
• He was 14 years old when his father was assassinated in 1968 (Miller Center).
• After his father’s death, Kennedy struggled with drug abuse and was arrested for marijuana possession at age 16 (Britannica).

The pattern: the Kennedy family legacy is a double-edged sword — public adoration paired with private trauma that shaped RFK Jr.’s early life.

What condition does RFK Jr. have?

Spasmodic dysphonia

• RFK Jr. has spasmodic dysphonia, a neurological disorder causing strained or broken speech (Wikipedia (community-edited encyclopedia)).
• In his 40s, he developed adductor spasmodic dysphonia, which causes quavering speech.
• He said he traveled to Kyoto, Japan, for a procedure involving a titanium bridge inserted between his vocal cords (Wikipedia).

Brain worm infection

• He also suffered a brain worm infection (neurocysticercosis) from a pork tapeworm (Wikipedia).
• The brain worm was discovered in 2012; he experienced cognitive symptoms.
• In a 2012 divorce-court deposition, he attributed neurological issues to a worm in his brain and to mercury poisoning from eating large amounts of tuna (Wikipedia).
• The Washington Post reported that Kennedy’s campaign had not released medical records that would verify his account of the worm-related illness (Wikipedia).

The implication: the public has only Kennedy’s own word and limited secondary sources for the full picture of his health history.

How did RFK Jr. get a brain worm?

Source of infection

• RFK Jr. contracted a pork tapeworm (Taenia solium), likely from eating undercooked pork (Wikipedia).
• The larval stage traveled to his brain, causing neurocysticercosis.
• He reported memory loss, mental fog, and disorientation.
• He eventually recovered after treatment, but the worm died in his brain.

Health impact and treatment

• In 2010, Kennedy began experiencing severe short- and long-term memory loss and mental fog, according to reporting summarized in secondary sources (Wikipedia).
• He said he recovered after medical treatment, but the worm’s death in his brain left residual issues.
• No independent medical records have been released to confirm the timeline or treatment (Wikipedia).

The catch: the story is compelling but rests almost entirely on Kennedy’s self-reporting, with no corroborating medical records from the treating physicians.

How is Arnold Schwarzenegger related to the Kennedys?

Marriage to Maria Shriver

• Arnold Schwarzenegger married Maria Shriver in 1986 (Wikipedia (community-edited encyclopedia)).
• Maria Shriver is the daughter of Eunice Kennedy Shriver and Sargent Shriver.
• Eunice Kennedy Shriver was President John F. Kennedy’s sister.
• Thus, Schwarzenegger is a Kennedy in-law.

Kennedy family ties

• Schwarzenegger’s marriage to Maria Shriver made him part of the extended Kennedy political dynasty.
• He served as Governor of California (2003–2011) and remained active in Republican politics.
• Despite the divorce in 2021, his children still carry the Kennedy connection.

What this means: the Kennedy network extends far beyond blood — marriage has brought in figures like Schwarzenegger, linking Hollywood and politics in a uniquely American way.

Do RFK Jr. kids talk to him?

Relationships with children

• RFK Jr. has six children from two marriages (HHS.gov (official agency biography)).
• Some reports suggest estrangement from certain children due to his controversial views (Britannica (established reference work)).
• His daughter Kathleen (Kick) has publicly discussed his brain worm incident (Wikipedia (community-edited encyclopedia)).
• His son Conor was briefly involved with Taylor Swift.

Public statements from family members

• Kick Kennedy has spoken about her father’s health issues in interviews.
• Other children have maintained privacy, making the degree of estrangement unclear.
• No family member has publicly confirmed a complete break.

The trade-off: public life brings scrutiny of private relationships, and the Kennedy family’s fame amplifies every rumor of rift.

Did Taylor Swift date RFK’s son?

Conor Kennedy relationship

• Taylor Swift dated Conor Kennedy (RFK Jr.’s son) in the summer of 2012 (Wikipedia (community-edited encyclopedia)).
• Conor Kennedy was 17, Taylor Swift was 22 at the time.
• The relationship ended after a few months.
• Swift also dated other Kennedy family members, but this was the most publicized.

Age gap controversy

• The age difference (17 and 22) sparked public discussion at the time.
• Conor Kennedy was still a minor in some states, though the relationship was legal in Massachusetts where the age of consent is 16.
• Swift’s team did not comment on the age gap.

Why this matters: the intersection of pop culture royalty and political dynasty created a media frenzy that still surfaces in trivia questions today.
