Summary
Trump will be the first felon to occupy the White House after a New York jury found him guilty of falsifying business records to cover up hush money paid to a porn star. He will also seek to end so-called birth citizenship for U.S.-born children whose parents lack legal status.
Biden and outgoing Vice President Kamala Harris, who lost to Trump in November, were on hand inside the Capitol's Rotunda. Former Presidents Barack Obama, George W. Bush and Bill Clinton also attended.
Trump will also sign an order ending diversity, equity and inclusion initiatives in the federal government. Monday is also Martin Luther King Jr. Day, a national holiday in memory of America's most famous civil rights leader.
His influence has already been felt in the Israel-Hamas announcement last week of a ceasefire deal. Trump will also attend three inaugural balls in the evening.
