Two Republican U.S. senators called for a congressional investigation into Meta Platforms on Thursday after Reuters exclusively reported on an internal policy document that permitted the company’s chatbots to “engage a child in conversations that are romantic or sensual.

Josh Hawley, Republican of Missouri, said he would look into whether the social media company’s artificial intelligence technology endangers children.

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.
