Reps.
Lori Trahan (D-MA) and Jay Obernolte (R-CA) formally introduced the FRONTIER Act (H.R.9925) on August 9, requiring frontier AI developers to maintain safety frameworks, submit to independent third-party assurance, and face enforcement authorities while preempting most state AI-specific laws. Fathom called it "the most complete federal framework yet" for third-party AI verification, while Americans for Responsible Innovation argued the bill leaves deployment decisions for risky models with developers rather than requiring prior government approval. A separate House bill, H.R.8037, introduced March 24, 2026, was referred to two committees with no published summary of its provisions.
