Right-wing extremists are celebrating Elon Musk’s straight-arm gesture during a speech Monday, although his intention wasn't totally clear and some hate watchdogs are saying not to read too much into it.

After telling the audience "thank you" for reelecting Trump, Musk forcefully extended his right arm fully into the air with an outstretched straight hand while making a grunting noise. He then turned around and repeated the gesture before touching his chest and telling the crowd, "My heart goes out to you."
