The episode traces the law’s origins, examines the traditional role of the US Treasury Department's Office of Foreign Assets Control (OFAC), and analyzes a case heading to the Supreme Court that could reshape how tariffs are imposed during declared national emergencies.

As Co-Chair of Jenner & Block's National Security and Crisis Practice and former Chief Counsel at OFAC, Rachel guides multinational companies and institutions through the complex landscape of US sanctions, export controls, and national security regulations.
