Elon Musk has slapped down a salacious claim from his own AI fact checker involving Katie Miller, the wife of top Donald Trump aide Stephen Miller.

Grok, Musk's AI chatbot integrated into X, responded to a screenshot of an X posting purported to be from Musk, which appeared to mock Stephen Miller by saying 'just like I took your wife.'

The chatbot answered that the post 'likely existed and was deleted.'

Musk disputed this, sounding exasperated as he responded: 'No, it's fake ffs [face palm emoji]. I never posted this.'
