President Donald Trump indefinitely postponed signing an executive order on AI after last-minute pushback from major technology executives and policy figures. The order would have created a voluntary pre-release vetting process for advanced AI models—up to 90 days—through testing by national security agencies. Reporting indicates David Sacks, Elon Musk, and Mark Zuckerberg led a rapid lobbying effort arguing the rule could interfere with U.S. leadership in AI and potentially slow innovation. Officials from multiple federal departments had already spent weeks negotiating the order’s language, and several AI companies—including Anthropic and OpenAI—had expressed support for the voluntary vetting concept. The pause increases uncertainty for universities and research labs planning AI compliance and safety workflows aligned to federal guidance, particularly where campus systems may rely on similar vendor model-release assumptions.
