Donald Trump moved swiftly to impose his will on the U.S. government as he reclaimed the presidency on Monday (January 20), taking steps to curb immigration, slash environmental regulations, and withdraw from an international climate treaty.

Cheered by a crowd at an indoor rally, Trump sat at a desk as he signed a series of executive orders in leather dossiers, 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.

He said he would sign more such orders when he reached the White House.

Earlier in the day, Trump, 78, took the oath of office in the Capitol Rotunda, the symbol of U.S. democracy that was invaded on Jan. 6, 2021, by a mob of Trump supporters intent on reversing Trump's 2020 loss to Joe Biden.

Trump was expected to pardon hundreds of those supporters who have been imprisoned for their actions.
Trump portrayed himself as a savior chosen by God to rescue a faltering nation. His inauguration amounts to a triumphant return for a political disruptor who survived two assassination attempts and won the election despite a criminal conviction and a prosecution stemming from his efforts to overturn his 2020 election loss.

Trump's initial executive orders revoked Biden administration policies governing artificial intelligence and electric vehicles, among others. He also imposed a freeze on federal hiring and ordered government workers to return to the office, rather than working from home.
