The European Commission has ramped up its investigation into Elon Musk’s X social network after the tech mogul criticized European governments in recent weeks, and just days before President-elect Donald Trump is set to return to the White House.

The European Commission said on Friday it was stepping up its investigation into whether Elon Musk's social media network X breached EU rules on content moderation with requests for information and an order for it to retain relevant documents.

The EU on Friday demanded X provide more details about its algorithms as part of its wide-ranging probe into the platform, as Elon Musk's outbursts on European politics ramp up pressure for the bloc to act.
