After telling the audience "thank you" for reelecting Trump, Musk appeared to grab his chest and then 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 again and telling the crowd, "My heart goes out to you."

Mr Musk is in charge of Mr Trump's newly created Department for Government Efficiency (DOGE). Elon Musk's starring role in the new Donald Trump administration was confirmed as he appeared front and centre of his inauguration proceedings - and witnessed him pledge a mission to Mars.
