RFK Jr faces calls for criminal investigation after New Samoa letters contradict Senate testimony on vaccines

US Health Secretary Robert F. Kennedy Jr. is facing renewed political and legal scrutiny after newly obtained documents appeared to contradict his previous statements to the Senate about a controversial 2019 trip to Samoa.

The documents, reported by The Guardian and the Associated Press, have prompted Senator Ron Wyden and government watchdog group American Oversight to call for an investigation into whether Kennedy made false statements to Congress during his confirmation process.

At the center of the controversy is Kennedy’s repeated assertion during Senate confirmation hearings that his trip to Samoa had “nothing to do with vaccines.” Newly released correspondence, however, shows Kennedy discussing plans to examine Samoa’s use of the measles, mumps and rubella, or MMR, vaccine before making the trip.

The dispute has reopened questions about Kennedy’s Senate testimony, his history of vaccine activism and the political consequences he could face as pressure for an investigation grows.

New Samoa letters raise questions about RFK Jr’s Senate testimony

The controversy stems from documents obtained following a Freedom of Information Act lawsuit. According to reports, one letter written by Kennedy to Samoa’s then-prime minister before his 2019 visit explicitly discussed studying issues connected to the country’s MMR vaccine.

The correspondence reportedly used the terms “vaccine” or “vaccination” multiple times and proposed an assessment related to what had happened with Samoa’s MMR vaccination programme.

Those documents appear to conflict with Kennedy’s statements during his 2025 Senate confirmation hearings. When questioned about the Samoa trip by Democratic senators, Kennedy repeatedly maintained that the purpose of his visit was unrelated to vaccines and was instead connected to medical informatics and digital health records.

The newly revealed correspondence has intensified criticism from Democratic lawmakers, who argue that the documents raise serious questions about whether Kennedy accurately represented the purpose of the trip to Congress.

Senator Ron Wyden calls for criminal investigation into RFK Jr

Senator Ron Wyden of Oregon has become one of the most prominent voices calling for further action following the release of the documents.

Wyden said he would press for a criminal referral and investigation into whether Kennedy violated laws governing false statements to Congress. The senator’s comments came after reporting indicated that Kennedy’s written communications before the Samoa trip were inconsistent with his later testimony about its purpose.

Government watchdog group American Oversight has also requested that the US Department of Justice investigate whether Kennedy made unlawful false statements to Congress.

The calls for an investigation do not mean Kennedy has been charged with a crime. Any potential criminal case would depend on investigators and prosecutors determining whether his statements met the legal standard for a prosecutable false statement.

Legal experts quoted in the reporting have noted that knowingly making material false statements to Congress can potentially carry criminal consequences, even when a witness is not under oath.

Why RFK Jr’s 2019 Samoa trip remains controversial

Kennedy’s visit to Samoa has remained a major source of controversy because it occurred during a period of significant concern about vaccination rates and public health on the Pacific island nation.

Before the trip, Samoa had experienced the deaths of two children after they received improperly prepared MMR vaccines. Authorities determined that human error was involved, and the vaccination programme was eventually resumed.

Kennedy was at the time associated with Children’s Health Defense, an organisation known for its opposition to aspects of vaccine policy. His communications with Samoan officials and his visit later became part of a broader debate about vaccine misinformation and its influence on public health decisions.

Months after Kennedy’s visit, Samoa experienced a devastating measles outbreak that sickened thousands and killed 83 people, most of them young children, according to the reports.

Public health experts and critics have argued that vaccine hesitancy played a major role in the country’s vulnerability to the outbreak. Kennedy has disputed claims that his visit was responsible for influencing Samoan vaccination decisions.

HHS rejects allegations that RFK Jr lied to Congress

The Department of Health and Human Services has strongly rejected the allegations against Kennedy.

An HHS spokesperson previously said Kennedy’s 2019 visit to Samoa was unrelated to vaccines and described claims that the newly revealed letters prove he lied to Congress as false and defamatory.

That response sets up a direct dispute between Kennedy’s defenders and critics over how his written communications should be interpreted alongside his Senate testimony.

The White House and HHS response will likely remain a central part of the political debate as Democratic lawmakers continue to push for accountability.

At this stage, there has been no public announcement that the Department of Justice has opened a criminal investigation into Kennedy over the Samoa trip or his confirmation hearing statements.

Could RFK Jr face legal or congressional consequences?

The controversy could extend beyond the immediate calls for a criminal investigation.

Legal and congressional experts cited in reports said Kennedy’s statements could potentially become the subject of future congressional hearings or other oversight actions, particularly if control of either chamber of Congress changes after future elections.

The federal statute of limitations for certain false-statement allegations involving Congress may also be relevant to any future legal action.

For now, the central issue remains whether Kennedy’s statements during his confirmation hearings can be reconciled with the language contained in the newly obtained Samoa correspondence.

The case has become another major political flashpoint surrounding Kennedy, whose leadership of the Department of Health and Human Services has already placed him at the centre of fierce national debates over vaccines, public health and federal health policy.

As pressure mounts from Democratic lawmakers and advocacy groups, the question is no longer limited to what RFK Jr did in Samoa in 2019. It now focuses on whether his explanation of that trip to the US Senate could expose him to a formal investigation in the years ahead.
