Mr. Musk has fallen out with prominent right-wing Americans who say they are worried that their agenda may be sidelined in favor of his own — and that he is willing to silence them on X.

WASHINGTON − Elon Musk is keeping the pressure on European leaders. Musk frequently wields his 211.5-million-follower account on X, the social media platform he bought for $44 billion in 2022, to air political grievances and promote far-right issues.

Musk, who has used X to amplify conspiracy theories and promote far-right talking points in the U.S., has more recently set his sights on Europe.

The Trump ally has flooded X with posts criticizing European politicians, causing a diplomatic conundrum for the continent’s leaders.

Martin Burndle said he was tempted to leave X (formerly Twitter) for good after recent comments by Elon Musk, generating both praise and criticism.

While Mark Zuckerberg and Elon Musk never did face off in that cage match, "Uncle Elon" has bested Zuck in the political arena, becoming one of the most powerful unelected figures in modern US history.
