Trump will be sworn in with his hand on a family Bible and the so-called "Lincoln Bible" (which was also used by Barack Obama).
Here's a reminder of the text of the oath of office that U.S. presidents take on their inauguration. The text of the U.S. presidential oath of office is enshrined in the U.S. Constitution. It is administered by the chief justice of the U.S. Supreme Court, and reads as follows:
I, [FULL NAME], do solemnly swear (or affirm) that I will faithfully execute the office of President of the United States, and will to the best of my ability, preserve, protect, and defend the Constitution of the United States. So help me God.
As we get ready for the inauguration ceremony to begin, here's video of the meeting at the White House of Trump and Obama with their wives.
Incoming first lady Melania Trump and Karen Pence have been introduced to the crowd ahead of the ceremony.
Our VOA colleagues report that chants of "USA! USA!" could be heard as the huge crowd awaited the start of the inauguration ceremony. But it's very quiet now aside from the announcer and the Marine band as the audience awaits the announcement of Obama and then Trump.
Outgoing President Obama and outgoing Vice President Biden have been announced to the crowd.
That is the last four "ruffles and flourishes" from the Marine band -- to denote the high honor of the presidency -- that Obama will get as president.
Vice President-elect Mike Pence has been announced and is on the platform for the ceremony.
President-elect Donald J. Trump has been announced to the crowd assembled for the inauguration, and was preceded onto the platform by senior Republican leaders.
