The Trump administration faces a Supreme Court challenge on Wednesday over its use of tariffs, an economic policy that has upended global trade.

This case, which has been described by the President in epic terms, questions the legality of Trump’s signature economic policy - and poses one of the biggest existential threats to his second term so far.

In today’s episode, we speak to small business owners across the US, and to BBC business reporter Natalie Sherman, who will be at the Supreme Court this week.
