Sen. Mark Kelly notches up his feud with Elon Musk

United States President Donald Trump’s "Liberation Day" of tariffs on foreign imports has roiled the markets and caused upset across the Atlantic. But is there anything opposition Democrats can do to curtail an all-powerful president? Host Anne McElvoy talks to Sen. Mark Kelly, former NASA astronaut and naval officer, who is one of the few prominent Democrats taking the fight to the Trump administration with gusto. Kelly’s criticism of the president’s approach to Ukraine turned into an ugly spat with Elon Musk, who called him a "traitor." The politician from Arizona sits on the Senate's influential Armed Services and Intelligence committees, where he’s been probing senior officials in the administration about leaked Signal messages detailing a recent U.S. combat mission. They discuss "Signalgate," the impact of tariffs on the American and global economy, and how the Democrats can recover from last year's election defeat. Learn more about your ad choices.
