Grok, the artificial-intelligence chatbot produced by Elon Musk -owned xAI, this week began posting antisemitic messages in response to user queries, drawing condemnation from Jewish advocacy groups and raising concern about the AI tool. The antisemitic posts -- some of which have been deleted -- are being addressed, Musk said on Wednesday.

Now, as Grok comes under fire for hate speech, its parent company is facing a lawsuit for potentially violating the Clean Air Act.

Hours later, on Wednesday, X CEO Linda Yaccarino resigned from the company after just two years at the helm, though it wasn’t immediately clear whether her departure was related to the Grok issue.

The cable was first reported by The Washington Post.

"This is just the reality of the 21st century with AI and fake stuff that's going on," he said.
