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

The Anti-Defamation League has declared that Musk’s gesture was “not a Nazi salute.” Stewart tried to puzzle it out: “Maybe that was Elon’s attempt at ‘dabbing on the haters.’”

Elon Musk offered Donald Trump supporters what looked a lot like a Nazi salute on live TV at Trump's post-swearing-in inauguration rally.

Stewart took on Trump’s news-filled Inauguration Day (full video, below) during Monday’s episode of Comedy Central’s The Daily Show. During Stewart’s 15-minute opener, he mocked the tech billionaires in attendance, President Joe Biden’s last-minute pardons of his family, Elon Musk’s controversial crowd salute and, of course, Trump’s speech.

Among the guests at Donald Trump's second inauguration in Washington, D.C. today were three billionaire tech CEOs: Amazon's Jeff Bezos, Tesla's Elon Musk, and Meta's Mark Zuckerberg. They were also joined by Google CEO Sundar Pichai and Apple CEO Tim Cook.

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.
