The letter responded to House Democrats Greg Casar and Doris Matsui, who had contacted OpenAI in August seeking details about the incident and what safeguards the company had in place. OpenAI did not include a log of the hack in its reply, drawing criticism from Representative Casar. "Your unwillingness to provide members of Congress with the information we requested is deeply concerning and signals to us that your company is not treating these cybersecurity incidents with the seriousness required," Casar wrote in a separate message to OpenAI on Wednesday.
