Elon Musk invested millions of dollars to help Donald Trump’s reelection campaign through the political action committee America PAC. The result was a massive door-knocking campaign in critical swing states and million-dollar giveaways to voters who signed a petition. Musk held rallies and town halls across Pennsylvania, spoke at Trump’s Madison Square Garden rally, and was alongside the president-elect at Mar-a-Lago on election night.Now Musk has been picked to help lead a new Department of Government Efficiency, with the goal of cutting government spending and streamlining regulations. Tech reporter Trisha Thadani spoke with Martine Powers about Musk’s political affiliations and his role in a future Trump administration and how it could benefit Musk’s companies. Today’s show was produced by Ariel Plotnick and edited by Maggie Penman.
