The DOJ filed to intervene in X’s challenge to the EU fine in the General Court in Luxembourg.
Why it matters: The move puts the U.S. government on the side of a major American tech platform in a European regulatory fight. It could also signal how far Washington is willing to go when U.S. companies face overseas enforcement.
- The DOJ filed a request on Sept. 24, 2026, to intervene in the General Court in Luxembourg.
- X Corp. and Elon Musk are seeking to annul the European Commission’s Dec. 5, 2025 decision.
- The Commission fined X €120 million under the Digital Services Act for transparency violations.
- Assistant Attorney General Brett A. Shumate said the case raises U.S. concerns about extraterritorial enforcement.
The U.S. Justice Department asked the EU General Court in Luxembourg to let it intervene in X’s challenge to a €120 million fine the European Commission imposed under the Digital Services Act.
The Commission said on Dec. 5, 2025, that X had violated the DSA and that the penalty reflected the nature, gravity and duration of those infringements. X and Elon Musk are seeking to annul that decision before the General Court, which is part of the Court of Justice of the European Union system.
In its filing announcement, the DOJ said the U.S. has an interest in protecting American companies from foreign extraterritorial enforcement action. Assistant Attorney General Brett A. Shumate said the Commission was trying to expand its authority beyond its jurisdiction, according to the department's statement.
Reuters reported that the U.S. government filed in support of X's effort to annul the penalty after a two-year investigation under the DSA. The Commission has said the fine relates to issues including deceptive verification, advertising transparency and researcher access to public platform data.
The dispute adds another point of friction in transatlantic debates over platform regulation. Brussels says its digital rules are nationality-neutral, while Washington has repeatedly criticized EU tech enforcement as discriminatory toward U.S. firms.
By the numbers
- €120 million - the fine the European Commission imposed on X.
- Dec. 5, 2025 - the date of the Commission decision X is challenging.
- Sept. 24, 2026 - the date the DOJ filed its intervention request.
Yes, but: The DOJ’s filing supports X’s challenge, but it does not mean the U.S. is a party to the underlying Commission enforcement action.
What's next: The General Court will decide whether to allow the DOJ to intervene in the case.
