Paris, France — asked the French authorities Elon Musk appears to be answering questions as part of an investigation into his social media platform X, Paris prosecutors said Monday, as authorities searched X’s office in the French capital.

“Invitations for voluntary interviews on April 20, 2026 in Paris were sent to Mr. Elon Musk and Ms. Linda Yaccarino, in their capacity as de facto and de jure managers of Platform X at the time of the event,” the Paris prosecutor’s office said in a statement.

Meanwhile, French cybercrime authorities searched X’s offices in Paris, prosecutors said.

The subpoenas for Musk and Yaccarino and the search of X’s office were related to an investigation launched in January 2025 into complaints about how X’s algorithm recommends content to users and collects data, prosecutors said. Officials have previously expressed concern that the way X operates could lead to political interference.

The investigation is to ensure that X complies with French laws, and the prosecutor added that it was expanded last year after reports that X allowed users to share sexually explicit images generated by artificial intelligence without consent and Holocaust denial content.

X and Musk dismissed the French investigation and similar investigations by the European Union and British authorities as baseless, politically motivated attacks on free speech.

Yaccarino resigned as CEO of X last July after two years at the helm of the company.

The investigation is led by the cybercrime department of the prosecutor’s office, in cooperation with the French police and the joint European police agency Europol.

CBS News investigation found at the end of last month yes it is Tom is great on Musk’s X platform still allowed users in the US, UK and EU to digitally undress people without their consent, despite the company’s public promises to stop the feature.

The Grok chatbot, both through its standalone app and for premium X account holders using the platform, allowed people to use artificial intelligence to edit images of real people and show them in revealing clothing like bikinis.

A request for comment on the findings of the CBS News investigation was met with an apparent automated response from Musk’s company xAI, which said only, “Lies from legacy media.”

Scrutiny of documents about Grok has increased rapidly in recent months, with warnings from the British government X could face a UK-wide ban if it fails to block the “bikini-fy” tool, and EU regulators announce their own investigation into the Grok AI editing function at the end of January.

CBS News found that Grok was still allowing users to digitally undress people in photos weeks after X he said earlier in Januarywhich he had, “implemented technological measures to prevent the (@)Grok account on X globally from allowing the editing of images of real people in revealing clothing such as bikinis. This restriction applies to all users, including paid subscribers.”
