Owner of X and world’s first trillionaire Elon Musk attacked French presidential candidate Marine Tondelier on Thursday, after the Greens party leader said French authorities should be able to suspend the platform during electoral campaigns in case of foreign interference.

“I demand that she be shut down for treason against France!” Musk wrote on X, prompting a strong reaction from Tondelier.

“France does not need lessons in patriotism from a foreign billionaire who thinks he gets to decide which European political leaders should be silenced. Democracy is not for sale. Not even to the richest man in the world,” she responded.
