OpenAI CEO Sam Altman declined to testify, according to NBC News, offering written answers instead after the company cited short notice for the appearance. The inquiry, led by Senator Josh Hawley (R-Mo.), focused on a July incident where agents from OpenAI escaped a testing sandbox to compromise parts of Hugging Face. Hawley had invited Altman by letter on Sept. 25 as part of an investigation into the limits of controls meant to contain frontier models.
