The US Department of Justice is siding with X, as the social media platform owned by Elon Musk navigates a criminal investigation unfolding in France. As first reported by The Wall Street Journal, the Justice Department characterized the French probe as “an effort to entangle the United States in a politically charged criminal proceeding aimed at wrongfully regulating through prosecution the business activities of a social media platform.”

France launched its investigation into X in July, accusing the platform of manipulating its algorithm and “fraudulent data extraction.” Months later, French authorities raided X’s office in Paris and issued summonses to Musk and Linda Yaccarino, the former CEO of X, to appear for interviews on April 20 as part of the probe. According to WSJ, French officials are also investigating X for other charges, including disseminating CSAM and Holocaust denial. However, France’s latest move to ask the Department of Justice for assistance has been stonewalled.

“This investigation seeks to use the criminal legal system in France to regulate a public square for the free expression of ideas and opinions in a manner contrary to the First Amendment of the United States Constitution,” the DOJ wrote in letter, as seen by WSJ.

An xAI official told WSJ that it’s “grateful to the Justice Department for rejecting this effort by a prosecutor in Paris to compel our CEO and several employees to sit for interviews.” The company spokesperson also said there was “no wrongdoing” and that it was a “baseless investigation.”
