U.S. President Donald Trump faces an arduous task delivering on his Inauguration Day promise of a "Golden Age of America" in the face of a closely split Congress, inevitable lawsuits and recalcitrant world leaders.

After taking the oath of office, Trump outlined a series of sweeping executive orders, the first steps in enacting a far-reaching agenda to expand America's territory, curb immigration, boost fossil fuel production and roll back environmental regulations.

Trump's allies and advisers have been drafting executive orders and agency regulations for months. They argue privately and publicly they are better prepared to enact their vision than they were during Trump's 2017-2021 term, when Republican infighting and a lack of foresight led to setbacks in the courts and in Congress.
