RFK Jr. pledges to end 'chemtrails'

Robert F. Kennedy Jr. said in a June 2 video posted on social media that he would stop “geoengineering #chemtrails” and work with President Donald Trump on prosecutions tied to the claim. The remarks extended a line of argument Kennedy had already made publicly in 2025, when he said he believed the Defense Advanced Research Projects Agency, or DARPA, was involved in spraying harmful materials into the sky. No evidence for that claim was provided in Kennedy’s earlier comments or in the public materials reviewed for this article. Federal agencies and outside fact-checkers have for years said the white streaks behind aircraft are contrails, not evidence of a secret spraying program. ### What exactly did Kennedy say this week? Kennedy said on June 2 that he would end what he described as “geoengineering #chemtrails” and would work with Trump on prosecutions, according to the social-media post described in the source briefings. The post drew supportive responses online, including one quoted reply that said, “HOPE SO. WE NEED THIS POLICY ASAP, WORLDWIDE!!!,” and had about 2,900 likes in replies that day, according to the briefing and the linked X post. (poynter.org) Kennedy had already made similar claims on April 29, 2025, during a town hall hosted by Phil McGraw, known as Dr. Phil. In that appearance, Kennedy said, “It’s done, we think, by DARPA,” and added, “I’m going to do everything in my power to stop it,” according to PolitiFact and Poynter reports published in May 2025. (x.com) ### What is the “chemtrails” claim he is invoking? The “chemtrails” theory has circulated since the 1990s and holds that governments or other actors are secretly dispersing chemicals or metals from aircraft for purposes such as weather control, public health manipulation or other covert aims. Newsweek, PolitiFact and Poynter each described the claim as a conspiracy theory and said Kennedy had publicly entertained it. (poynter.org) EPA says on its contrails information page that “chemtrails” and geoengineering are terms often inaccurately used as alleged synonyms for contrails. The agency says its goal is to provide “clear, science-based information” in response to public questions and misconceptions. ### What do federal agencies say those streaks behind planes actually are? (poynter.org) EPA says contrails are long, thin clouds that form behind aircraft at high altitudes under certain atmospheric conditions. The agency’s fact sheet says contrails are composed primarily of water in the form of ice crystals and do not pose direct health risks to humans. (epa.gov) UCAR materials on contrail microphysics say contrails can persist and spread when the surrounding atmosphere is saturated with respect to ice. EPA’s text-only explainer says aircraft exhaust contains water vapor and particles, and that contrails can sustain and spread into cirrus-like clouds in ice-supersaturated regions. ### What about Kennedy’s earlier claim about jet fuel? (epa.gov) PolitiFact reported in May 2025 that Kennedy said chemicals were being put into jet fuel and sprayed from the sky. The outlet said Kennedy’s office provided no evidence for the statement and rated the claim “Pants on Fire.” The Federal Aviation Administration says fuel dumping is rare. (opensky.ucar.edu) In a 2022 report to Congress, the FAA said there were more than 25.5 million flights over the United States per year on average between fiscal 2015 and fiscal 2019, and an annual average of 15 reported fuel dumps in that period. ### Has any federal agency backed the chemtrails allegation? (politifact.com) EPA says it is “not aware of any deliberate actions to release chemical or biological agents into the atmosphere,” according to an archived agency page on contrails. That page also says contrails are visible ice-particle clouds that can persist depending on atmospheric conditions. (faa.gov) DARPA did not respond to PolitiFact’s request for comment when Kennedy made the accusation in 2025, according to that report. No public evidence surfaced in the materials reviewed here showing that DARPA, HHS or another federal agency had confirmed Kennedy’s allegation. June 2 is the date of Kennedy’s latest post, and the EPA and FAA reference pages cited above remain available as the main federal public records on contrails and fuel dumping. (19january2021snapshot.epa.gov) Any next formal step from Kennedy or the Trump administration would most likely appear through HHS, the White House or a federal enforcement announcement.
