Shortly after I met Lina Khan, her cellphone rang. The call was from a representative of a national organization, regarding a speech it had asked her to give. Khan was courteous on the phone, but she winced momentarily after hanging up. “That was the American Bar Association,” she confessed. “I don’t know if I’ve passed the bar yet.”

This feeling—that Khan’s ideas are in high demand slightly before her time—has characterized much of her life lately. In the past year, the 29-year-old legal scholar’s work has been cited approvingly by the lefty, rabble-rousing congressman Keith Ellison and by a Trump-appointed assistant attorney general, Makan Delrahim. She has been interviewed by NPR and written op-eds for The New York Times.
