Donald Trump was sworn in as the 47th president of the United States on Monday in a ceremony inside the U.S. Capitol's Rotunda, returning to the White House after defeating Joe Biden in a historic rematch that saw an incumbent president denied a second consecutive term. Trump, 78, took the oath of office before a packed crowd of lawmakers, dignitaries, and supporters, with Chief Justice John Roberts administering the ceremony. Former presidents Bill Clinton, George W. Bush, and Barack Obama attended, continuing a tradition of peaceful transitions of power. The ceremony, moved indoors due to cold weather, marked several firsts: Trump became the first president to return to office after a defeat, while his running mate J.D. Vance became vice president after being sworn in by Justice Roberts. In a notable show of corporate support, top technology executives including Apple's Tim Cook, Amazon's Jeff Bezos, and Tesla's Elon Musk sat in prominent positions near the stage. Prior to the ceremony, Biden and Trump shared a limousine ride to the Capitol, maintaining another inaugural tradition despite their fierce rivalry. Biden, 82, issued several last-minute pardons before departing office, including one for Indigenous activist Leonard Peltier. Read more of this story at Slashdot.
