Musk, the billionaire Trump ally who is playing a public role in the incoming administration, posted in support Friday of Alternative for Germany, or AfD, after the German government collapsed this week.

Musk, who spent hundreds of millions on Trump's bid to return to the White House, is poised to take a leading role in reshaping the U.S. government.

Musk’s tweet was promoting another tweet from Naomi Seibt a German climate change denier who rose to prominence as the anti-Greta Thunberg. Seibt has also promoted conspiracy theories and been accused of being antisemitic, according to the Guardian, a claim she denies.
