Self-proclaimed Christian Nationalist Marjorie Taylor Greene is fuming after Elon Musk’s AI bot cast doubt on her Christian values. The Georgia congresswoman proudly declared her Christian beliefs in an X post Friday—only to be undercut by Grok, Musk’s AI chatbot, which replied, “Whether she’s ‘really’ a Christian is subjective.”

Rep. Marjorie Taylor Greene argued with X’s AI software after the bot suggested her claim of being a Christian doesn’t always align with her actions. The feud began Friday when the far-right wing congresswoman took exception to Grok fact-checking her commitment to her faith by saying her support for conspiracy theories and Christian nationalism calls her beliefs into question.

Congresswoman Marjorie Taylor Greene recently criticized the AI bot Grok after it responded to questions about her publicly identifying as a Christian.
