Donald Trump has been sworn in for a second term as president of the United States at noon local time (17:00 GMT) in Washington, DC.
Because of frigid temperatures, Trump relocated the ceremony indoors, under the Capitol rotunda, rather than on the marble steps outside, as usual.
Trump, the first US president convicted of criminal charges, replaced Democrat Joe Biden following his victory over Kamala Harris in November’s presidential election.
The 78-year-old’s return to the White House comes four years after his previous re-election attempt ended in defeat.
In the lead-up to Monday’s inauguration, Biden pardoned several individuals feared to be targets under Trump’s incoming administration: Dr Anthony Fauci, General Mark Milley and members of the January 6 committee, including Liz Cheney.
