Donald Trump will be sworn in as president of the United States on Monday, ushering in his second term in office and capping one of the most astounding political comebacks in American history. Trump, a Republican, has pledged to sign a flurry of executive orders on subjects ranging from border security to oil and gas production on his first day in office. Thousands of spectators without tickets are expected to fill the National Mall and watch the ceremony on large video screens. Trump has broken with precedent and invited several foreign leaders to the ceremony, including Argentina's president and Hungary's Viktor Orban. After a lunch with congressional leaders at the U.S. Capitol, Trump will proceed down Pennsylvania Avenue in a motorcade to the White House, accompanied by a procession of military regiments, school marching bands, floats, and citizens' groups. Trump is preparing a flood of executive orders and directives that could total more than 100 for day one and beyond, including orders to increase energy production and issue pardons for defendants convicted for their participation in the Jan. 6, 2021, siege of the U.S. Capitol. The official events are financed by Trump's inauguration committee, with donations from companies like Amazon, Meta Platforms, Apple, and Uber. On the eve of the inauguration, Trump is set to hold a campaign-style rally in downtown Washington.
