Social media was set ablaze Monday after Elon Musk — the billionaire owner of Texas-based SpaceX and Tesla — appeared to give a Nazi salute during President Trump's inauguration rally. Indeed, two back-to-back salutes during a post inauguration rally at the Capital One Arena in Washington D.C. set the internet ablaze with speculation from social media users that Musk was welcoming fascism with a "sieg heil" salute. You be the judge.
