WATCHUS White House National Policy Framework for AI and Congressional TRUMP AMERICA AI Act Introduce Federal Preemption Debate

The White House released a nonbinding National Policy Framework for AI on March 20, 2026, emphasizing national uniformity and targeted federal preemption of state AI laws; two days prior, Sen. Blackburn introduced the updated 291-page TRUMP AMERICA AI Act seeking to codify Trump-era AI executive orders and constrain state-level regulation. Democratic opposition crystallized around the GUARDRAILS Act, which would repeal the national framework EO and block state preemption, making near-term bipartisan federal AI legislation unlikely.
