Newly obtained emails cast doubt on US Health Secretary Robert F. Kennedy Jr.'s sworn testimony that his 2019 trip to Samoa (a Pacific island nation) had "nothing to do with vaccines." A message from Kennedy's colleague Dr. Michael Graven, then chief information officer of the anti-vaccine group Children's Health Defense, explicitly described the visit as a "mission" to analyse medical records tied to a "discontinuity in vaccinations" on the island. A measles outbreak several months after Kennedy's visit killed 83 people, mostly young children, and Samoan officials later said Kennedy's presence had bolstered the credibility of anti-vaccine activists — lending the new evidence significant weight as Democrats call for Kennedy to be held accountable for allegedly lying to Congress.
