'RFK Jr. Lied to Congress': Criminal Probe Sought Over Samoa Trip Linked to 83 Measles Deaths
"He told us his Samoa trip had nothing to do with vaccines—now this letter shows that was false," Sen. Ed Markey said of President Donald Trump's health and human services secretary.
US Health and Human Services Secretary Robert F. Kennedy Jr. on Thursday faced calls for a criminal investigation after newly published documents appear to contradict his repeated testimony during Senate confirmation hearings that his 2019 trip to Samoa, which is linked to 83 measles deaths, “had nothing to do with vaccines.”
The advocacy group American Oversight on Thursday asked the US Department of Justice to investigate whether Kennedy knowingly made materially false statements during his 2025 Senate confirmation hearings. The request follows the publication of a January 2019 letter, signed by Kennedy and addressed to Samoa’s then-prime minister, Tuilaʻepa Saʻilele Malielegaoi, that explicitly proposed a vaccine-focused assessment of the Pacific island nation’s measles, mumps, and rubella (MMR) program.
“Robert F. Kennedy Jr. repeatedly testified before two separate Senate committees that his trip to Samoa had nothing to do with vaccines. But a letter he wrote to Samoa’s prime minister six years earlier appears to contradict that testimony,” American Oversight executive director Chioma Chukwu said Thursday in a statement.
“Congress relies on truthful testimony to do its job, particularly on matters as consequential as public health," Chukwu added. "If Kennedy lied to the Senate while seeking confirmation as the nation’s top health official, the Justice Department must investigate and hold him accountable.”
Questioned by Sen. Ron Wyden (D-Ore.) before the Senate Finance Committee, Kennedy said his trip had “nothing to do with vaccines,” describing it instead as an effort to introduce a medical informatics system to digitize the nation's health records.
The following day, when Sen. Ed Markey (D-Mass.) pressed him on the same issue before the Senate Health, Education, Labor, and Pensions Committee, Kennedy again said his trip had “nothing to do with vaccines.”
Markey's office released a statement Thursday noting that Kennedy "traveled to Samoa in 2019 to promote disinformation about the measles vaccine. Shortly after his trip, Samoa experienced a deadly outbreak of measles that killed over 80 people and has been attributed to mass vaccine disinformation."

Of the 83 measles deaths during the outbreak, 72 were children under the age of 5. More than 1,860 hospitalizations in Samoa have been linked to the outbreak.
“New documents confirm what we already knew: RFK Jr. lied to Congress," Markey said. "He told us his Samoa trip had nothing to do with vaccines—now this letter shows that was false, just like it was false when he denied his role in the deadly outbreak that followed."
"This is a pattern, not a slip," he added. "RFK Jr. has lied to the Senate, lied to the American people, and jeopardized the health of children to advance his anti-vaccine agenda. He should never have been confirmed, and he cannot be trusted to run [the US Department of Health and Human Services] for even one more day."
Democratic Hawaii Gov. Josh Green, who is a physician, was invited by the Samoan government to help lead the measles response and recovery in the South Pacific archipelago.
“Misinformation and measles are a deadly combination—I saw that firsthand in Samoa," Green said on Thursday. "The truth is, this is a disease we know how to prevent. The MMR shot is the only proven and effective way to prevent the spread of measles."
"Vaccines save lives," he added. "Our public health decisions must be guided by doctors, scientists, and evidence—not conspiracy theories or political convenience. We owe it to every family to protect our children and communities, and make sure no one else dies from a preventable disease.”
The group 314 Action, which recruits, trains, and works to elect Democrats with expertise in science, published a statement Thursday noting that "now, America is facing its worst measles crisis in decades, and two more Americans have lost their lives to a disease we have long known how to prevent."
Public health experts have warned that the US is on track to lose its measles elimination status, which the country achieved in 2000, and blame the regression on declining vaccination driven by misinformation and conspiracy theories, including that vaccines are dangerous and even deadly.
Earlier this month, President Donald Trump signed an executive order overhauling federal recommendations for children that calls for separating the MMR vaccine into three individual shots.
"The only thing ‘lethal’ about vaccines is listening to RFK Jr.’s lies about them," said 314 Action. "America needs more leaders like Gov. Green who are willing to stand up to Trump and RFK Jr. and put public health over politics. We won’t stop fighting until RFK Jr. is fired or removed from office.”
