President Donald Trump’s invocation of the Alien Enemies Act last week kicked off a battle with the courts that’s getting more heated by the day. On Tuesday, he called U.S. District Judge James E. Boasberg “crooked” and a “radical left lunatic” and suggested he should be impeached. Then, Supreme Court Chief Justice John G. Roberts Jr. issued a rare public rebuke of the president, saying impeachment is “not an appropriate response” to a judicial decision. Senior politics reporter Aaron Blake speaks with Supreme Court reporter Justin Jouvenal and White House reporter Natalie Allison about the legal and political calculus behind Trump’s fight with the courts. And they also weigh in on the partial ceasefire deal for Ukraine brokered by the president and his Russian counterpart. Today’s show was produced by Laura Benshoff.
