Trump cancels AI executive order signing ceremony after Musk, Zuckerberg, and Sacks each call him directly to oppose 90-day review window

President Trump cancelled a planned May 21, 2026 signing ceremony for an AI executive order after Elon Musk, Mark Zuckerberg, and David Sacks each called him directly the previous night. The draft order had required a 90-day pre-release review window for frontier AI models. All three callers have direct financial stakes in AI markets: Musk owns xAI, Zuckerberg leads Meta's AI division, and Sacks co-founded Craft Ventures with broad AI portfolio investments. The White House confirmed the delay and said it was reworking the order to address industry concerns.
