President Donald Trump just declared to thousands of American manufacturing workers in Michigan, “You were sold out and betrayed by globalist politicians” who let foreign countries “steal your jobs, pillage your factories, and then loot the crown jewels of American industry.” Under Trump’s leadership, we are reducing our dependence on foreign countries for materials essential to our national and economic security, as we fight to bring back millions of American manufacturing jobs.During my time working for Trump on the campaign and as White House principal deputy press secretary, we traveled the nation and visited communities hollowed out by foreign countries cheating. From steel and electronics plants in Pennsylvania and Ohio, to heavy machinery and auto parts manufacturers in Wisconsin and Michigan, plants that once supported hundreds of thousands of American manufacturing jobs were decimated.Fortunately, Trump has seen this playbook before, with godless communists and their allies using unfair trade practices to attack American industries such as steel, aluminum, solar panels, semiconductors, and textiles. Our president developed the Trump Trade Doctrine to stop foreign countries from ripping us off and to maintain America’s place as the world’s superpower.
