A day after Reuters reported that Meta's AI rules permitted children to have "sensual" chats, a Republican senator launched an investigation into the tech giant. On Friday, Missouri Sen. Josh Hawley posted a letter he sent to Mark Zuckerberg along with the announcement of the investigation.

An internal Meta policy document reveals the social-media giant’s rules for chatbots, which have permitted provocative behavior on topics including sex and race.

Reuters reviewed an internal Meta document detailing the company's standards and guidelines for training its platform chatbots and generative AI assistant, Meta AI, and says the company confirmed the document was authentic.
