Joe Biden sworn in as nation's 46th president at inauguration

Joe Biden has officially become the 46th president of the United States. Biden took the oath of office just before noon Wednesday during a ceremony at the U.S. Capitol. The presidential oath was administered by U.S. Supreme Court Chief Justice John Roberts. Biden was sworn in using a Bible that has been in his family since 1893 and was used during his swearing-in as vice president in 2009 and 2013. The 5-inch thick Bible, which could be seen on a table next to Biden’s chair on the dais, has a Celtic cross on its cover and was also used each time he was sworn- n as a U.S. senator. Biden’s late son, Beau, also used the Bible for his own swearing-in ceremony as attorney general of Delaware and helped carry the Bible to his father’s 2013 ceremony.
