Elon Musk faced an immediate backlash after making two one-armed gestures during a speech celebrating Donald Trump’s presidential inauguration at the Capital One Arena in Washington, D.C. Online observers and some public figures compared the movement with a Nazi salute, while others said the interpretation misrepresented an enthusiastic expression of thanks.

Musk had been thanking Trump supporters for the election result when he placed his right hand on his chest and extended that arm upward in front of him. He then turned toward people seated behind the stage and repeated the action. Around the second gesture, he told the audience that his heart went out to them and credited them with helping secure the future.

The sequence spread quickly through social media and television coverage. Critics, including historian Ruth Ben-Ghiat, said the gesture resembled a Nazi salute. Other commentators described it as evocative of fascist imagery without claiming certainty about Musk’s intent. The controversy was intensified by praise for the gesture from some extremists and by Musk’s growing political prominence as a close Trump ally.

Musk dismissed the accusations in a post on X, the social media platform he owns. He said his critics needed better tactics and described comparisons to Hitler as tired. His speech itself did not contain a reference to Nazism or fascism, and the supplied reporting did not establish that he intended the movement as an ideological salute.

The Anti-Defamation League, an organization that campaigns against antisemitism, urged restraint. It assessed the action as an awkward gesture made in excitement rather than a Nazi salute and encouraged opposing sides to extend some benefit of the doubt. That judgment did not end the dispute: other Jewish representatives and scholars reached different conclusions about the movement and the significance of the surrounding context.

The episode drew international attention because Musk had recently endorsed Germany’s far-right Alternative for Germany party and had become deeply involved in pro-Trump politics. German Chancellor Olaf Scholz, asked about the comparison, emphasized that support for extreme-right positions was unacceptable in Germany.

Musk, the head of Tesla and SpaceX, had also been selected to help lead the Trump administration’s proposed Department of Government Efficiency. That combination of private influence, control of a major communications platform and a visible political role magnified scrutiny of his conduct.

The central disagreement remained unresolved in the immediate reporting: the physical action was visible and repeated, but its intended meaning was contested. A neutral account therefore distinguishes the observable gesture from the serious historical interpretation applied to it, and records both Musk’s rejection of that interpretation and the divided assessments from outside observers.
