The US Justice Department has informed French law enforcement that it will not provide assistance in their investigation of Elon Musk's social media platform X. This decision comes in response to a letter from the DOJ's Office of International Affairs, which expressed concerns about the implications for First Amendment rights. The investigation, initiated by Paris prosecutors, focuses on allegations of algorithm abuse and fraudulent data extraction by X. French lawmakers and advocacy groups have raised complaints leading to this scrutiny. The DOJ's letter argues that the French requests aim to politically charge a criminal proceeding against a US business, potentially infringing on free expression rights. Officials from xAI, Musk's artificial intelligence company, welcomed the DOJ's stance, hoping it will lead to the termination of what they describe as a baseless investigation. The US Department of Justice, French authorities, and xAI have not provided immediate comments on the matter.
