EU industry chief Thierry Breton told billionaire Elon Musk in a letter on Monday he must comply with EU law ahead of Musk's interview with U.S. presidential candidate Donald Trump on social media platform X, Paralel.Az reports citing Reuters.

The interview, scheduled for 8PM Eastern Time (0000 Tuesday GMT), will also be accessible to users in the EU, Breton wrote, adding: "In this context, I am compelled to remind you of the due diligence obligations set out in the Digital Services Act (DSA)."

"DSA obligations apply without exceptions or discrimination to the moderation of the whole user community and content of X (including yourself as a user with over 190 million followers) which is accessible to EU users and should be fulfilled in line with the risk-based approach of the DSA, which requires greater due diligence in case of a foreseeable increase of the risk profile", Breton wrote in his letter.
