The U.S. Department of Justice has declined to assist French prosecutors in their investigation into X, refusing to facilitate questioning of Elon Musk and several employees. This marks the third request for judicial cooperation from France this year, which the U.S. rejected, citing First Amendment concerns. The French investigation, initiated in January 2025, has expanded from examining potential political bias in X's algorithm to include allegations of child sexual abuse imagery and Holocaust denial. Despite the U.S. refusal, French prosecutors assert the investigation will continue independently.
