Gavin Newsom’s California AI order advances a state-mandated “kill switch” while challenging President Trump’s preference for fewer federal controls on the technology.
California Gov. Gavin Newsom signed the executive order Friday, directing companies behind advanced “frontier” AI models to develop a shutdown mechanism, Fox Business reported. Frontier models are the most advanced AI systems under development.
The order also moves California’s AI auditor registry and oversight program forward by more than a year. The state now plans to begin it in December 2027 instead of January 2029.
Newsom said he would assemble a panel of experts to examine what an AI “kill switch” should mean. His order therefore accelerates state oversight before California has settled the scope and operation of its central mandate.
The governor also used the announcement to fault the federal government and President Donald Trump. Newsom said Washington had failed in “its responsibility to protect Americans” by declining to impose broader AI rules.
Newsom acknowledged that the term “kill switch” lacks one settled meaning. He said it “means a lot of things depending on who you talk to” and that California wants to determine what kind of framework could work.
That leaves major questions unanswered. Fox Business did not identify the exact technical requirements for AI companies, the conditions that could trigger a shutdown, or the process for deciding when a model had gone rogue.
Newsom framed speed as a virtue, arguing that California could not afford to wait for Congress or the Trump administration. In announcing the order, he said:
“We're not waiting to act, we’re going to speed up our work on substantial and responsible AI oversight before it's too late. We’re going to do this thoughtfully but with urgent velocity; the stakes are too high to wait or delay action,”
The promise to act “thoughtfully” now rests beside a mandate whose core term still requires a panel to define it. For companies expected to obey the order, that gap between urgency and precision matters.
California’s existing AI laws establish a system in which independent organizations assess AI systems for safety and possible risks. Newsom’s order speeds up that oversight structure while recommending stricter controls on companies developing the technology.
Newsom said no comprehensive federal law requires AI companies to disclose dangerous incidents. He also accused Trump of rejecting regulation despite calls for limits from Anthropic CEO Dario Amodei, OpenAI CEO Sam Altman and xAI CEO Elon Musk.
In a video posted to his personal YouTube channel, Newsom directly challenged the president:
“There's still no comprehensive federal law, none, requiring AI companies to report dangerous incidents when they happen, and President Trump has rejected calls for new regulation. No new regulation. Let it rip. He's dead wrong,”
Trump took the opposite position. On Truth Social, he called the risks surrounding AI a “hoax” and argued that presidential leadership offered the necessary safeguard.
Trump wrote:
“The only control or ‘guardrails’ that AI needs is a STRONG AND SMART (High IQ!) PRESIDENT, and the U.S.A. has that, in spades!”
The dispute does not fall along a simple party line. Louisiana Republican Sen. John Kennedy tried during the same week to introduce a federal AI “kill switch” bill, but Kentucky Republican Sen. Rand Paul blocked the effort.
Paul argued that Congress should not rush a plan governing an entire industry without hearing from its leaders. His objection focused on the legislative process and the breadth of the proposed regulation.
Fox Business did not provide the executive order’s title or identifying number. It also did not specify which California laws the order relies upon or where Newsom signed it.
The precise duties imposed on frontier-model companies remain unclear as well. The available details do not explain who would control the shutdown tool, what standard would define a rogue model, or how California would enforce the requirement.
Those are not minor technical questions. They determine how much authority the state may exercise and what companies must do to comply.
Newsom has chosen speed and state control while the federal debate remains unsettled. But urgency does not excuse vague rules, especially when government orders private companies to build tools whose reach officials have yet to define.
