A Democracy Drive Thread
Gutting research, denying climate change and vaccines, purging scientists, and elevating quackery — a chronological, sourced record of the administration's assault on science and expertise.
From climate data scrubbed off government websites to vaccine panels purged and replaced, from defunded labs to pseudoscience promoted from the nation's top health office, this thread tracks the war on science and expertise. Entries are in chronological order, each with sources.
January 27, 2025
Trump again pulled the U.S. out of the Paris climate agreement and set about dismantling federal climate work — moves Project 2025 spelled out in detail.

As a measles outbreak grew past 1,000 cases — producing the first U.S. measles deaths in a decade, including two unvaccinated children in Texas — Kennedy called the situation “not unusual,” gave only a lukewarm endorsement of the MMR vaccine, promoted unproven treatments, and falsely suggested the vaccine itself causes deaths “every year.”
June 9, 2025
Kennedy abruptly removed all 17 members of the CDC’s Advisory Committee on Immunization Practices — the panel that recommends vaccines and shapes what insurers must cover — calling it a “clean sweep,” then named replacements including prominent vaccine skeptics. The American Medical Association said the unprecedented move undermined a process that had “saved countless lives.”

Under RFK Jr.'s HHS, the FDA approved updated COVID-19 vaccines only for adults 65 and older and high-risk people, narrowing access for healthy younger Americans who had been eligible.

A judge halted Kennedy's attempt to reshape the CDC childhood immunization schedule, finding he likely exceeded his authority.
April 21, 2026
Hegseth scrapped the long-standing requirement that U.S. troops be vaccinated against influenza, over health experts' objections.
June 24, 2026
Defense Secretary Pete Hegseth made flu vaccination voluntary in April 2026, ending a requirement that had stood for U.S. troops since 1945. By late June, a flu outbreak at Joint Base San Antonio–Lackland — where only about 40% of new trainees had been vaccinated when it began — had grown from 159 cases to 275 in roughly a week, with recruits hospitalized. The military then quietly reinstated mandatory flu shots for Army, Navy and Air Force recruits.

May 22, 2025
Kennedy’s “MAHA” commission released its marquee report on children’s health — and researchers quickly found it cited multiple studies that do not exist, with dozens more broken or wrong citations bearing the hallmarks of AI generation (the marker “oaicite” appeared in footnotes).
