U.S. AI regulation order collapsed amid White House infighting and lobbying by Musk and Zuckerberg

美国 AI 监管令突然告吹内幕：白宫内讧，马斯克、扎克伯格游说特朗普

Trump canceled a planned AI executive order on May 22 that would have given the U.S. government authority to evaluate AI models before public release; the post says David Sacks, Mark Zuckerberg, and Elon Musk opposed the draft and lobbied against it.

Why it matters: HKR-H/K/R all pass: the story has political conflict and a concrete pre-release review mechanism. It stays below P1 because the draft text, scope, and cross-source confirmation are not disclosed.
