Stocks end modestly lower after reeling from Trump's latest threats to escalate his tariff fight

The Dow Jones Industrial Average fell 349 points, or 0.9%, and the Nasdaq composite rose 0.1%. The Dow was earlier down as many as 1,700 points following even worse losses worldwide on worries that Trump’s tariffs could torpedo the global economy. It then surged to a gain after a rumor circulated that Trump may pause his tariffs. But the White House quickly called that fake news, and Trump then threatened to raise tariffs further on China.
