Elon Musk’s controversial gesture, which some interpreted as a Nazi-style salute, drew criticism from Trump’s political opponents and energized fans on the far right.

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

President Donald Trump's "first buddy," Elon Musk, was seemingly everywhere in D.C. on Inauguration Day. Where (and with whom) was the billionaire?

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."
