US Backs Elon Musk’s Challenge to €120 Million EU Fine Against X

The US government has formally sought to intervene in Elon Musk and X’s legal challenge against a €120 million ($137 million) fine imposed by the European Union, escalating a dispute over how far Brussels can regulate American technology companies operating in Europe. The US Department of Justice filed an application with the EU’s General Court on Thursday in support of X Corp. and Musk’s efforts to annul the European Commission’s December 2025 decision.
