President Donald Trump is sounding an upbeat note about his tariffs even as the stock market reacted by falling more than 1,600 points. He said Thursday, “I think it's going very well.” Trump likened the United States to a sick patient in need of surgery and said the market drop after his announcement was to be expected. U.S. stocks led a worldwide selloff after the Republican president’s tariff announcement on Wednesday. Trump announced a minimum tariff of 10% on imports, with the tax rate running much higher on products from certain countries like China and those from the European Union.
