CHICAGO (AP) — Five secretaries of state are urging Elon Musk to fix an AI chatbot on the social media platform X, saying in a letter sent Monday that it has spread election misinformation.

The top election officials from Michigan, Minnesota, New Mexico, Pennsylvania and Washington told Musk that X’s AI chatbot, Grok, produced false information about state ballot deadlines shortly after President Joe Biden dropped out of the 2024 presidential race.

While Grok is available only to subscribers to the premium versions of X, the misinformation was shared across multiple social media platforms and reached millions of people, according to the letter. The bogus ballot deadline information from the chatbot also referenced Alabama, Indiana, Ohio and Texas, although their secretaries of state did not sign the letter. Grok continued to repeat the false information for 10 days before it was corrected, the secretaries said.

The letter urged X to immediately fix the chatbot “to ensure voters have accurate information in this critical election year.” That would include directing Grok to send users to CanIVote.org, a voting information website run by the National Association of Secretaries of State, when asked about U.S. elections.

“In this presidential election year, it is critically important that voters get accurate information on how to exercise their right to vote,” Minnesota Secretary of State Steve Simon said in a statement. “Voters should reach out to their state or local election officials to find out how, when, and where they can vote.”

X did not respond to a request for comment.

Grok debuted last year for X premium and premium plus subscribers and was touted by Musk as a “rebellious” AI chatbot that will answer “spicy questions that are rejected by most other AI systems.”

Social media platforms have faced mounting scrutiny for their role in spreading misinformation, including about elections. The letter also warned that inaccuracies are to be expected for AI products, especially chatbots such as Grok that are based on large language models.

“As tens of millions of voters in the U.S. seek basic information about voting in this major election year, X has the responsibility to ensure all voters using your platform have access to guidance that reflects true and accurate information about their constitutional right to vote,” the secretaries wrote in the letter.

Since Musk bought Twitter in 2022 and renamed it to X, watchdog groups have raised concerns over a surge in hate speech and misinformation being amplified on the platform, as well as the reduction of content moderation teams, elimination of misinformation features and censoring of journalists critical of Musk.

Experts say the moves represent a regression from progress made by social media platforms attempting to better combat political disinformation after the 2016 U.S. presidential contest and could precipitate a worsening misinformation landscape ahead of this year’s November elections.
