Geral Ford took the presidential oath of office.
In January 2009, he took the oath on the Bible that had been used by President Abraham Lincoln. In January 2013, he used two bibles-- the Lincoln Bible and a traveling bible used by Dr. Martin Luther King.
I know Lyndon Johnson took the oath of office aboard Air Force One in Texas at Love Field right after Kennedy was pronounced dead
The oath of office is administered by the chief justice, usually at the inauguration ceremony in Washington DC.
I have read many reasons why this was done. Conspiracy theorist come with a lot of imagination these days. The first oath was done over the 1861 Bible President Lincoln used wich is not mandatory as only a tradition started by The first President George Washington. I believe an oath is like baptism. Once you baptise you dont need to baptise again, you just follow along with your faith the rest of your life. Obama took an oath over the Bible and one is just enough for the rest of his presidential mandate.
