The blossoming relationship between President Donald Trump and tech titan Elon Musk was on full display throughout Monday's inauguration ceremonies.

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."
