US Backs X's Challenge to EU's 120 Million Euro Fine
The US Department of Justice has filed to intervene in X's lawsuit against the EU's 120 million euro Digital Services Act fine, arguing Brussels improperly expanded regulatory authority over American companies. The EU has reaffirmed its sovereign right to enforce digital safety rules, signaling readiness to defend the fine in court.
Quick Facts
- US DOJ filed application to intervene in X's lawsuit
- EU Commission fined X 120 million euros for DSA violations
- X challenged the fine alleging insufficient investigation and biased prosecution
- X submitted proposals to address EU concerns, accepted in July 2026
- EU reaffirmed commitment to defend the fine in court


The US Department of Justice has filed an application to intervene in X's lawsuit against a 120 million euro fine imposed by the European Commission in December 2025, marking an escalation in transatlantic tensions over digital regulation. The DOJ argues that the EU Commission has improperly expanded its regulatory authority to target American companies operating outside its jurisdiction, stating the fine could set a precedent affecting US tech platforms globally. Assistant Attorney General Brett Shumate said the US will not tolerate "regulatory overreach" aimed at controlling "American engines of innovation and economic growth."
The EU Commission fined X for violating the Digital Services Act, citing three breaches: deceptive design of the blue checkmark system that misled users about account verification status, insufficient transparency in advertising practices, and failure to provide researchers adequate access to platform data. The fine followed a two-year investigation and represents the first enforcement action under the EU's DSA framework. X filed suit in February 2026, contesting the investigation's sufficiency, the Commission's interpretation of the law, and alleging biased prosecution. The DOJ's intervention, approved after consultation with the State Department, suggests the Trump administration views the case as having broader implications for US technology companies operating in Europe.
Parallel to the legal dispute, X has submitted proposals addressing the EU's concerns, which the Commission accepted in July 2026 as "an important step in the right direction." The platform has publicly clarified that blue checkmarks now denote premium subscription status rather than account verification, and has committed to accommodating the EU on other points of criticism. However, the lawsuit seeking annulment of the original fine remains active. The case will be heard at the EU's General Court in Luxembourg.
The European Commission has signaled its intent to defend the fine vigorously. Commission Spokesman Thomas Regnier stated Friday that drafting legislation to protect EU citizens is a "sovereign right," and that the Commission applied its rules "objectively, transparently, and with a solid case." The Commission emphasized it has substantial evidence available and will allow the court to decide the matter. EU officials characterize the DSA as necessary for consumer protection, while the Trump administration and affected US companies have criticized it as censorship and regulatory overreach targeting American innovation.
Why This Matters
The case establishes precedent for regulatory jurisdiction over US technology companies in Europe. The outcome will affect how the Digital Services Act is enforced against major social media platforms and may shape compliance costs for US tech firms operating in the EU. The US intervention signals potential trade tensions if courts uphold the fine structure. Measurable stakes include potential similar fines under DSA framework, platform design requirements, and data access obligations for researchers.
