Trump Tariffs Blocked by the Supreme Court (What’s Next?)

18 minutes

Last Friday, the Supreme Court struck down President Trump’s IEEPA tariffs in a landmark 6-3 decision. In this episode of The Deduction, hosts Kyle Hulehan and Erica York break down what the ruling actually means, from how collections could be refunded to how the administration is already scrambling to put new tariffs in place. Erica walks through why businesses may face even more uncertainty in the near term as a messy patchwork of replacement tariffs takes shape.
