Trump was losing in the courts. He’s not anymore. In the early months of the administration, the courts were proving a powerful check on President Trump, blocking many of his boldest actions. But those were the lower courts. In the past few months, the Supreme Court has weighed in, and it has handed Trump win after win after win. So what do these decisions enable the president to do? And why is the Supreme Court giving Trump what he wants? To pull all this apart, I’m joined by Kate Shaw. She is a former Supreme Court law clerk, a professor at the University of Pennsylvania Carey Law School and a host of the “Strict Scrutiny” podcast. Note: This episode was recorded on Aug. 21, before Trump announced his intention to fire Lisa Cook from the Federal Reserve Board of Governors and before Immigration and Customs Enforcement re-arrested Kilmar Armando Abrego Garcia and began processing him for deportation to Uganda.

ICE now has the biggest budget of any law enforcement agency in America. “ICE and Customs and Border Protection have long been the most rogue, kind of renegade and certainly pro-Trump police agencies in the federal government,” explained Radley Balko, a journalist who’s covered policing for decades. “What I think we are seeing right now is Trump is attempting to build his own paramilitary force. They want people whose first, ultimate loyalty in this job is going to be to the president.” Balko is the author of “Rise of the Warrior Cop: The Militarization of America’s Police Forces.” And he’s been tracking the changes at ICE and the Trump administration’s escalating law-and-order tactics on his excellent newsletter, The Watch.

“Make America Healthy Again” is a great idea — somebody should try it. A lot of the concerns animating the MAHA movement — chronic disease, the unhealthiness of the American diet, how profits warp our health care system — are serious issues. But Robert F. Kennedy Jr. hasn’t taken major actions to address them. Instead he’s gutted funding for scientific research, including nearly $500 million dedicated to mRNA vaccine development, throwing a huge amount of possibly lifesaving research in limbo. How did we get here? What are the politics that allowed Donald Trump to preside over Operation Warp Speed, the single most successful pandemic mitigation policy, and then turn around a few years later to appoint Kennedy to undo it all? My colleague David Wallace-Wells has done incredible reporting on how pandemic policies have shaped our politics, culture and society. Rachael Bedard is a physician and a writer who has been thinking deeply about what MAHA represents and where the movement could find common ground with its critics.
