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.

Biden had planned to take a train into Washington on Tuesday ahead of Inauguration Day. But he scratched the plan amid security concerns after this month's riot at the U.S. Capitol.
Instead he flew into a military airbase just outside the capital and traveled via motorcade into a city that’s been flooded by some 25,000 National Guard troops.
