Are Trump’s Tariffs Lawful?

In this episode, Samuel Estreicher of the NYU School of Law and John Yoo of the UC Berkeley School of Law join to recap the oral arguments from the pair of challenges to President Trump’s tariffs and discuss whether International Emergency Economic Powers Act (IEEPA) authorizes the president to impose extensive tariffs on nearly all goods imported into the United States. Jeffrey Rosen, president and CEO of the National Constitution Center, moderates.
