During the first hundred days of Trump's presidency, policy focus centered on fulfilling campaign promises, including three major topics: immigration, trade, and employment. He signed multiple executive orders to strengthen border control, promote the US-Mexico border wall project, and restrict entry for individuals from certain specific countries. Economically, he advocated for 'America First,' withdrew from the TPP, renegotiated the North American Free Trade Agreement, and proposed a tax reform plan to reduce the burden on businesses and stimulate investment. Despite high administrative efficiency, some policies sparked controversy and legal challenges, leading to implementation setbacks. The hundred-day report card shows his leadership style is tough and pragmatic, valuing image and action, but also reveals challenges in coordinating with Congress and refining policies.
