Newsom orders California agencies to develop new AI safety plans after rejecting tougher law
California under Newsom has enacted several first-in-the-nation laws to curb the potentially existential risks of AI. In 2025 he signed Senate Bill 53, which requires large AI model developers to publish frameworks on how they manage safety incidents and assess catastrophic risk — defined as incidents involving 50 or more deaths, chemical or biological weapons or more than $1 billion of theft or damage. They also must report critical safety incidents to the state. Illinois and New York have similar laws.
