RFK Jr., a prominent figure in U.S. politics and the current head of the Health and Human Services Department, has shifted his focus from anti-vaccine claims to promoting a widely debunked theory that links 5G technology to health risks. The Department of Health and Human Services (HHS) has recently launched a public comment period to explore potential health effects of electromagnetic fields and wireless radiation from various technologies, including cellphones, Wi-Fi, smart meters, and autonomous vehicles. According to HHS, the initiative aims to identify gaps in current research and strengthen regulations to better protect public health. The 5G network, the most advanced cellular technology that connects devices to the internet, was rolled out nationwide in December 2019. Shortly after, in early 2020, the spread of the coronavirus led to online conspiracy theories suggesting a link between 5G and the virus. Similar claims had previously linked 5G to cancer in 2018, but these have been consistently refuted by scientific research. RFK Jr., who has previously promoted discredited theories about vaccines and autism, has now expressed concerns about the health impacts of 5G radiation. In a January interview with USA TODAY, RFK Jr. claimed that electromagnetic radiation from wireless devices poses a significant health risk, citing "literally over 10,000 studies" that supposedly show links to cancer, tumor growth, and other health problems. However, scientific consensus and major health organizations have repeatedly found no credible evidence supporting these claims. A 2024 review by the World Health Organization of 63 peer-reviewed studies found no justification for health concerns related to cellphone use. Similarly, the U.S. Centers for Disease Control and Prevention, which operates under HHS, states it has "no science to link health problems to cell phone use." HHS Press Secretary Grace Davis Jamison explained that the call for public comments is part of the MAHA (Make America Healthy Again) Strategy, which instructed HHS to examine research on electromagnetic radiation and health. This initiative coincided with RFK Jr. addressing the anti-vaccine group Children’s Health Defense, an organization he founded, which has opposed the installation of cell towers. During the event, RFK Jr. told the group they have "a friend in the White House," referring to his position at HHS.
