Trump signs order on Thursday, OpenAI closed-door meeting, AI must pass government review before release.

AIMPACT reports that the U.S. ONCD convened a closed-door meeting with OpenAI and others on May 19, 2026, to discuss the proposed signing of an AI executive order, which could be signed by Trump as early as Thursday. The new regulation is a voluntary pre-approval review framework, requiring sharing information with the government before public release, initially set for 90 days, with efforts to shorten it to 14 days before release. Standards for cutting-edge models are jointly defined by the NSA, ONCD, OSTP, and others, with the Department of Defense participating in classified assessments. Previously, Anthropic Mythos's zero-day vulnerability capabilities were seen as a driving factor.
