The mainstream media were at it immediately saying that Musk had delivered a Nazi salute as he put is hand to his chest, then extended it. "This is what victory feels like," Musk told the crowd. "Yeah! And, this was no ordinary victory. This was a fork in the road of human civilization, okay. There are elections that come and go, some elections are, you know, important. Some are not. But, this one — this one really mattered, and I just want to say thank you for making it happen, thank you."
Musk can then be seen placing his hand over his heart and appearing to give a salute to the crowd.
"My heart goes out to you," Musk added as he can be seen with his hand over his heart. "It is thanks to you that the future of civilization is assured. Thanks to you. We're going to have safe cities, finally, safe cities. Secure borders, sensible spending, basic stuff. And, we're going to take DOGE to Mars."
So, in the context this had nothing to do with Nazism. In fact, it is easy to find via Google pictures of Harris doing the same hand movement. Plenty of other woke Leftists have done as much.
