Weeks run Monday through Sunday, U.S. Eastern time. Enactment dates come from each law's official record; for a few laws not yet reviewed, the date is the last recorded action. Veto dates are the recorded action date. This page is rebuilt from our records, so a correction to any law shows up here too. Counts follow our methodology: published, AI-relevant bills, one per bill number, enacted when signed or otherwise made law. Data as of October 16, 2026.
