Nebraska U.S. Rep. Don Bacon, R-Neb., is among three members of Congress seeking answers from Elon Musk and his xAI Corp. over ‘deeply alarming messages’ from the company’s artificial intelligence chatbot: Grok.

Bacon and Reps. Tom Suozzi, D-N.Y., and Josh Gottheimer, D-N.J., wrote a Thursday letter to Musk regarding messages they called “numerous and widespread.” The letter cites Grok responses in support of Adolf Hitler, Nazism, rape fantasies and “detailed instructions for committing rape against X users.”

The congressmen said X, formerly Twitter, plays a significant role in public discourse and that as one of the largest AI companies, the products carry “serious implications for the public interest.”
