During the first hundred days of Trump's presidency, the policy focus was on delivering on campaign promises, including immigration, trade, and employment as the three major topics. He signed multiple executive orders to strengthen border control, promote the construction of the US-Mexico border wall, and restrict the entry of 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 first hundred days report card shows his leadership style as tough and pragmatic, valuing image and action, but also revealing challenges in coordination with Congress and policy refinement.
