WASHINGTON (Reuters) - Joe Biden was sworn in as president of the United States on Wednesday, offering a message of unity and restoration to a deeply divided country reeling from a battered economy and a raging coronavirus pandemic that has killed more than 400,000 Americans.

Standing on the steps of the U.S. Capitol two weeks after a mob of then-President Donald Trump's supporters stormed the building, Biden called for a return to civic decency in an inaugural address marking the end of Trump's tempestuous four-year term.
