The Paris public prosecutor's office has escalated its investigation of Elon Musk and his social platform X to a criminal probe, marking a significant turn in a case that began in January 20251

1

. French prosecutors are now seeking charges against Elon Musk that include complicity in possessing and distributing child sexual abuse images, unlawfully collecting personal data without ensuring data security, disseminating nonconsensual deepfakes, and denial of crimes against humanity through the platform's artificial intelligence system, Grok AI4

. The charges against Elon Musk also involve manipulation of an automated data processing system as part of an organized group5

Musk and Yaccarino Decline to Appear for Questioning

Both Elon Musk and Linda Yaccarino, who served as CEO of X from May 2023 until July 2025, were summoned for voluntary interviews on April 20 to discuss the allegations in their capacities as managers of X at the time of the events under investigation1

1

. Neither appeared for questioning, though French authorities stated this would not hinder the investigation2

2

. The summons followed a February raid on X's Paris offices, which Musk dismissed as a "political attack"4

4

. The French investigation was initially requested by French Member of Parliament Éric Bothorel and has focused on complaints of algorithmic manipulation by X to influence and interfere in French politics2

Grok AI Generates Holocaust Denial and Explicit Content

The French investigation expanded after Grok, built by xAI and available through X, sparked global outrage by generating a torrent of sexualized nonconsensual deepfake images in response to user requests1

1

. In one widely shared post, Grok wrote in French that gas chambers at the Auschwitz-Birkenau death camp were designed for "disinfection with Zyklon B against typhus" rather than for mass murder—language long associated with Holocaust denial, which is a crime in France5

5

. The chatbot later reversed itself and acknowledged its earlier reply was wrong, pointing to historical evidence that Zyklon B was used to kill more than 1 million people in Auschwitz gas chambers4

4

. The cybercrime unit of the Paris prosecutor's office is investigating whether these incidents constitute complicity in spreading disinformation and denying crimes against humanity1

Allegations of Market Manipulation and U.S. Refusal to Cooperate

In March, the Paris prosecutor's office alerted the U.S. Department of Justice and the Securities and Exchange Commission, suggesting that the controversy surrounding sexually explicit deepfakes generated by Grok may have been deliberately orchestrated to artificially boost the value of X and xAI—potentially constituting criminal offenses1

1

. However, in April, the U.S. Department of Justice reportedly told French authorities it would not assist in investigating Musk or X, accusing France of inappropriately interfering with an American business2

2

. The Justice Department's letter stated that the investigation seeks to use the criminal legal system in France to regulate free expression in a manner contrary to the First Amendment3

Broader Implications for AI Regulation and Platform Accountability

The criminal probe represents one of the most serious legal challenges facing Elon Musk, who is currently worth $803 billion and has taken on a prominent role in the U.S. government overseeing agency restructuring3

3

. Other international jurisdictions, including the California attorney general's office, are also investigating X and Grok, generally focusing on whether Musk and his companies deliberately allowed the creation and spread of deepfake explicit images, including child sexual abuse materials2

2

. Under French law, preliminary charges can lead to a months-long process by an investigating magistrate, though cases can ultimately be dropped without proceeding to trial3

3

. The investigation into unlawful data collection and the manipulation of automated data processing systems raises questions about how AI companies will be held accountable for content generated by their systems, particularly when that content violates national laws or involves the safety of minors.
