On November 25, 2025, the Trump EPA filed a brief in the U.S. Court of Appeals for the D.C. Circuit asking the court to vacate the Biden-era National Ambient Air Quality Standard for fine particulate matter (PM2.5)—tightened from 12 to 9 micrograms per cubic meter—by "confessing error" rather than following the Clean Air Act's required notice-and-comment rulemaking process. The move would eliminate a standard projected to prevent 4,500 annual premature deaths, 2,000 hospital visits, and 800,000 asthma cases by 2032. By requesting court vacatur instead of formal rulemaking, the EPA avoids the statutory requirement to publish reasoned explanations and allow public comment on the rollback.
The FBI's counterterrorism division contacted six Democratic members of Congress on November 25, 2025 to request interviews following President Trump's public accusations that they committed "seditious" acts. The six—Sens. Mark Kelly and Elissa Slotkin and Reps. Jason Crow, Maggie Goodlander, Chris Deluzio, and Chrissy Houlahan—had released a video reminding U.S. military personnel of their constitutional obligation to refuse unlawful orders, protected First Amendment speech in response to the Trump administration's strikes on Latin American targets. The inquiry came one day after the Pentagon threatened to recall Sen. Kelly to active duty for potential military charges.
