Neo-Nazis celebrate Elon Musk make two Nazi-like salutes during a speech to tens of thousands of Supporters of President Donald Trump on Monday.

“Elections come and go, some elections are important, some are not, but this one is very important,” Musk said during his speech inside the Capital One Arena in Washington DC, hours after the Trump was sworn in as the 47th president of the United States. “And I just want to thank you for making it. Thank you.”

At this point, Musk placed his right hand on his chest before extending it straight out with his palm facing down and his fingers touching, a gesture widely recognized as the “Salute in Rome.” Adopted by the fascist movement a century ago, it was most famously used by Adolf Hitler and the Nazi Party in Germany, and is still associated with the fascist right, especially in Italy.

After he first made the move, Musk then turned to the crowd members sitting behind him and, with his back to the camera, repeated the move.

“My heart goes out to you,” Musk added.

Musk shared a clip of his X speech but at the point where he made the first salute, the clip posted by Musk cut to a shot of the audience before returning to show him making the second salute.

Musk, X, and the Trump administration did not immediately respond to requests for comment.

The response from the neo-Nazi community around the world was swift and unanimous.

“Unbelievable things have happened,” Andrew Torba, the founder of Gab, a social media platform popular with antisemites and white supremacists, wrote on a photo of Musk giving the salute.

“The whole neo-Nazi movement seems to eat it up,” said Nick Martin, an investigative journalist who closely tracks extremist groups and runs an online publication The Informant. “He gave both the unmistakable Nazi salute and they got the message loud and clear.”

“WE ARE FUCKING BACK” the administrator of a Nazi meme channel on Telegram wrote under a clip of Musk giving the salute. Group members responded with the lightning bolt emoji, a prominent neo-Nazi reference in SS.

“I don’t care if it’s a mistake, I’m going to enjoy the tears,” Christopher Pohlhaus, the leader of American neo-Nazi group Blood Tribewrote on his Telegram channel under a gif of the Musk salute.

Keith Woods, a famous far-right influencer from Ireland who has repeatedly praised Musk, responded to the actions by writing X: “OK maybe woke up dead.”

Evan Kilgore, a right-wing political commentator, wrote in X: “Holy crap … is Elon Musk just Heil Hitler at the Trump Inauguration Rally in Washington DC … This is unbelievable.” Kilgore later wrote: “We’re back.”

Kilgore, who is a Holocaust denierworking as an ambassador for Charlie Kirk’s Turning Point USA. The conservative activist group hosted a pre-inauguration ball Sunday night that featured JD Vance, who was inaugurated as vice president today, and the president’s son, Donald Trump Jr.

Musk has accepted far-right ideology and figures around the worldincluding the jailed Islamphobic activist Tommy Robinson in the UK, for the past two years. Most recently, he promoted the German far-right political party Alternative for Germany. In an hour-long interview with party leader Alice Weidel earlier this month, Musk agreed to the wild conspiracy theory. that Hitler was a communist.
