The European Union is investigating social media company X over suspected violations of the Digital Services Act (DSA) in its first probe under the law.

“Today we open formal infringement proceedings against @X” under the Digital Services Act, European Commissioner Thierry Breton said Monday in a post on the platform formerly known as Twitter.

“The Commission will now investigate X’s systems and policies related to certain suspected infringements,” spokesperson Johannes Bahrke said at a news briefing in Brussels. “It does not prejudge the outcome of the investigation.”

The investigation will look into whether X failed to do enough to curb the spread of illegal content and whether measures to combat ” information manipulation”, especially through its crowd-sourced Community Notes fact-checking feature, were effective.

The probe will also consider issues with user interface, deceptive use of “verified’ accounts and lack of access to researchers.

“X remains committed to complying with the Digital Services Act, and is cooperating with the regulatory process,” the company said in a statement.
