President-elect Trump’s former adviser Steve Bannon has vowed to “take down” tech billionaire Elon Musk, calling him “truly evil.” In an interview with Italian newspaper Corriere della Sera, as highlighted by Mediaite, Bannon sharply criticized Musk, who was tapped by Trump to co-lead the “Department of Government Efficiency.” “I will have Elon Musk run out of here by Inauguration Day,” Bannon said. “He is a truly evil guy, a very bad guy. I made it my personal thing to take this guy down.” With Trump set to take office for the second time shortly, Musk’s influence in the next administration remains unclear. Bannon criticized Musk over the continued debate over H-1B visas. Musk is supportive of the work program that allows the U.S. to attract international talent. Trump’s base, however, is not supportive of the program, fueling a fight over the topic.
