During the first hundred days of Trump’s administration, the policy focus was on fulfilling campaign promises, including three major issues: immigration, trade, and employment. He signed multiple executive orders to strengthen border control, promote the U.S.-Mexico border wall project, and restrict entry for individuals from certain specific countries.
