FILE - In this July 26, 2018, file photo President Donald Trump speaks at the United States Steel Granite City Works plant in Granite City, Ill. Trump spent four years upending seven decades of American trade policy. He started a trade war with China, slammed America’s closest allies by taxing their steel and aluminum and terrified Big Business by threatening to take a wrecking ball to $1.4 trillion in annual trade with Mexico and Canada. Trump’s legacy on trade is likely to linger, regardless whether Joe Biden replaces him in the White House in January 2021. (AP Photo/Jeff Roberson, File)
