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.

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.

Hawley chairs the Senate Judiciary Subcommittee on Crime and Counterterrorism and said he was opening an investigation into Meta’s generative AI products with that power.
