Apple is working to get refunds for tariffs previously paid to the U.S. government but will reinvest any money it recovers in the country, Apple CEO Tim Cook said on Thursday. Apple has disclosed more than $3.3 billion in tariff costs during the second administration of U.S. President Donald Trump. During a conference call with analysts to discuss its quarterly financial results on Thursday, the company did not update that figure, nor provide a specific expected refund amount, but Cook said costs had been lower in the fiscal quarter ending March 28.
