WASHINGTON / PARIS — April 18, 2026
The U.S. Department of Justice has refused to assist French authorities in their investigation into tech billionaire Elon Musk’s social media platform X, according to reports by The Wall Street Journal and Reuters.
The decision, communicated in a formal letter from the DOJ’s Office of International Affairs, marks a significant escalation in tensions between the United States and France over the regulation of online platforms and free speech.
Why the US Refused
According to the DOJ, the French investigation conflicts with constitutional free speech protections in the United States.
In the letter, U.S. officials argued that the French case attempts to use criminal law to regulate online discourse, stating it is contrary to the First Amendment. They also described France’s request as an effort to involve the U.S. in a “politically charged” legal proceeding targeting a private American company.
The DOJ further said the requests from France risk improperly regulating the business activities of a social media platform through prosecution.
What the French Investigation Involves
French prosecutors have been investigating X since early 2025, focusing on several serious allegations:
- Algorithm manipulation — claims that X’s system may bias or distort content visibility
- Improper data extraction — concerns over how user data may have been accessed or used
- Illegal content — including hate speech, Holocaust denial, and explicit deepfake material, which are criminal offenses under French law
As part of the probe, authorities raided X’s Paris office in February 2026 and summoned Musk and other executives for questioning.
French officials reportedly made multiple requests to the U.S. for assistance, including efforts to compel testimony from Musk and company staff.
X and Musk’s Response
Representatives linked to Musk’s AI venture xAI welcomed the DOJ’s refusal, calling the French investigation “baseless” and expressing hope it would be dropped.
X has consistently denied wrongdoing and previously described French enforcement actions—including the office raid—as politically motivated.
A Wider Transatlantic Clash
The dispute highlights a growing divide between the U.S. and Europe over how to regulate major technology platforms.
- Europe (including France) has taken a stricter stance, enforcing laws against harmful or illegal online content
- The U.S. places greater emphasis on protecting freedom of expression, even when content may be controversial
Some activities under investigation in France—such as certain speech or content—are protected under U.S. law, complicating international cooperation.
