Donald Trump has been sworn in for a historic second term as president on Monday, pledging a blitz of immediate orders on immigration and the US culture wars as he caps his extraordinary comeback.
With one hand raised in the air and the other on a Bible given to him by his mother, the 47th US president solemnly took the oath of office beneath the huge Rotunda of the US Capitol.
Republican Trump and outgoing Democratic President Joe Biden had earlier traveled by motorcade together to the Capitol, where the ceremony was being held indoors and with a much smaller crowd for the first time in decades due to frigid weather.
Earlier, they and their spouses met for a traditional tea at the White House.
Trump was a political outsider at his first inauguration in 2017 as the 45th president, but this time around he is surrounded by America's wealthy and powerful.
