Elon Musk hit out at the European Union on Saturday after the European Commission imposed a large fine on his social media platform X.

On Friday, the EU hit X with a fine of 120 million euros ($140 million) for breaching its transparency rules, accusing the platform of misleadingly authenticating user accounts with blue ticks, withholding data from researchers and not transparently documenting advertisements placed on the platform.

The commission said the amount of the fine was proportionate to the infringement.

The fine also drew fire from US Secretary of State Marco Rubio.

"The European Commission's $140 million fine isn't just an attack on X, it's an attack on all American tech platforms and the American people by foreign governments," he posted on X on Friday.

Musk did not say whether he would seek legal action against the commission's decision.

He continued his attacks on the EU in a series of other posts, accusing it of censorship.
