Supreme Court hears arguments on presidential authority over tariffs

In the most significant economic case to reach the Supreme Court in years, the justices will weigh whether President Donald Trump acted lawfully when he imposed sweeping emergency tariffs against most trading partners. Those actions have been challenged by a group of small and medium-sized businesses, as well as a dozen states.

CNN chief Supreme Court analyst Joan Biskupic previews the arguments, and CNN’s Kate Bolduan speaks with former US Attorney Michael Moore. #CNN #News
