Online users shared videos showing Musk twice extending his hand outward from his heart but omitted his words explaining the gesture.

Grimes, Elon Musk's ex, has responded to the backlash of his controversial hand gesture, which is going viral. On Monday, the Tesla CEO took the stage in Washington, DC's Capital One Arena, beginning his speech by saying, "Thank you for making it happen. Thank you," followed by slapping his right hand on his chest and extending it in salute.
