U.S. Stocks Open Lower On Continued Political Uncertainty

U.S. stocks opened lower on Tuesday as investors continued to grapple with political uncertainty stemming from the newly inaugurated President Donald Trump's administration. Late Monday, Trump fired the acting attorney general, who declined to defend an executive order calling for a travel ban. The order, which was met with massive controversy, also spurred selling on Monday. Investors also watched the latest batch of corporate earnings, including from Exxon Mobil Corp. and Pfizer Inc. . The Dow Jones Industrial Average fell 72 points, or 0.4%, to 19,899. The S&P 500 lost 5 points to 2,276, a drop of 0.2%. The Nasdaq Composite index sank 17 points, or 0.3%, to 5,595.
