Biden sworn in as 46th US president without a hitch, mandating masks as his first order of business.
Democrat Joe Biden has been sworn in as President of the United States, vowing to end the "uncivil war" in a deeply divided country reeling from a battered economy and a raging coronavirus pandemic.
With his hand on a 12cm-thick heirloom Bible that has been in his family for more than a century, Biden took the oath of office administered by US Chief Justice John Roberts that binds the president to "preserve, protect and defend the constitution of the United States".
"Through a crucible for the ages, America has been tested anew, and America has risen to the challenge," Biden said in his inaugural address.
"Today we celebrate the triumph not of a candidate but of a cause: the cause of democracy... At this hour, my friends, democracy has prevailed."
