The Trump administration is facing a legal challenge at the US Supreme Court regarding the legality of its tariffs, with small businesses and states contending the tariffs are illegal. The challengers are demanding refunds for billions of dollars collected. Separately, the White House announced that China will ease its export ban on automotive computer chips. This measure is a key component of a new trade deal struck between US President Donald Trump and Chinese President Xi Jinping. In another matter, former US President Donald Trump pardoned crypto billionaire Changpeng Zhao last month, but later claimed in a CBS News’ 60 Minutes interview that he does not know him.
