During the 2016 primary season Trump defeated more than a dozen seasoned rivals to win the Republican nomination and went on to win the election over former Secretary of State Hillary Clinton. His campaign slogan was “Make America Great Again,” and he moved swiftly to reinvigorate “Buy American and Hire American” policies. He signed a major tax reform bill into law and directed the reduction of federal regulations intended to secure a long-running economic expansion and a historically low unemployment rate. His trade policies encouraged tariffs on foreign aluminum and steel and a series of renegotiations of trade agreements with Mexico, Canada, China, Japan, and South Korea.
