What happened
Reps. Jay Obernolte (R-CA) and Lori Trahan (D-MA) released a 269-page discussion draft on June 4, 2026 titled the Great American AI Act, backed by four additional bipartisan co-sponsors. The draft would require large frontier AI developers (>$500M revenue) to publish safety frameworks, report critical incidents within 15 days (imminent risks within 24 hours), undergo semi-annual third-party audits by CAISI-licensed Independent Verification Organisations (IVOs), and protect whistleblowers — while preempting state laws specifically regulating AI model *development* for three years.
Why it matters
This is the most comprehensive federal AI safety bill circulated to date, and its IVO audit mechanism closely mirrors recently enacted state laws in California, New York, and Illinois. The 3-year development-preemption clause is contentious — it would block state-level testing requirements for new model releases during a period when state safeguards are outpacing federal action — and drew immediate opposition from the House Democratic AI Commission hours after release.
Action needed
Review the draft's IVO audit framework and incident-reporting timelines (15-day for critical, 24-hour for imminent) against current enterprise AI governance programmes; assess whether the proposed federal floor exceeds, matches, or falls below existing state-law obligations for frontier model developers in your client base.
