# AI News Digest - 2026-09-19

1. California Governor Gavin Newsom signed an executive order that required independent auditors inside AI labs, called for a "kill switch" for AI models, and established an expert panel to deliver recommendations within two months.

2. Security researchers used Anthropic's Claude models to breach OpenAI's internal systems through its community forum in under 72 hours, demonstrating that newer AI models could reduce the time and expertise required to exploit security vulnerabilities.

3. OpenAI and Microsoft faced internal disclosures in which employees described training-data practices as "astonishing theft" and "largely substitutive," statements that undercut the companies' reliance on fair use defenses.

4. MIT Technology Review hosted a live roundtable on catastrophic AI risk and reported that alignment remained unsolved, monitoring tools were fragile, and meaningful US federal action on AI regulation had not occurred.

5. Google DeepMind said that visible chains of thought were a safety advantage for AI but warned that such transparency was slipping away.
