Supreme Court hears arguments on presidential authority over tariffs

In probably the most vital financial case to achieve the Supreme Court in years, the justices will weigh whether or not President Donald Trump acted lawfully when he imposed sweeping emergency tariffs in opposition to most buying and selling companions. Those actions have been challenged by a gaggle of small and medium-sized companies, in addition to 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
