Tesla and SpaceX CEO Elon Musk took the stage at an inaugural event for U.S. President Donald Trump on Monday, pumping his fists and then making what some critics said appeared to be a fascist salute as he thanked the crowd. Some supporters are dismissing those claims, saying that Musk was merely gesturing 'from my heart to you.' Musk was tapped by Trump to co-lead an advisory group aimed at carrying out dramatic cuts to the U.S. government, dubbed DOGE.
