The U.S. Supreme Court is set to hear arguments Wednesday on the legality of Donald Trump¡¯s unprecedented use of powers for sweeping global tariffs in a case striking at the heart of the president¡¯s economic agenda.

Since returning to the White House, Trump has invoked emergency economic powers to impose ¡°reciprocal¡± tariffs over trade practices Washington deemed unfair, alongside separate duties targeting his country¡¯s biggest trading partners: Mexico, Canada and China.

But these tariffs, a key prong of his ¡°America First¡± trade policy aimed at protecting and boosting U.S. industries, swiftly faced legal challenges.
