Trump ordered federal review of scientific manual used by federal judges
On July 20, 2026, President Trump posted on Truth Social directing "federal suspension and debarment officials" to review the National Academy of Sciences' Reference Manual on Scientific Evidence, calling its climate science content "fraudulent" and "bogus." The manual serves as a reference resource for federal judges evaluating scientific testimony. The Federal Judicial Center had already removed the manual's climate chapter in February 2026 under pressure from Republican state attorneys general; Trump's directive escalated that pressure by invoking executive contracting enforcement authority against the NAS.
