Donald Trump will place his hand on two Bibles during the swearing-in ceremony: the Lincoln Bible from 1861 and one gifted by his mother in 1955. The Lincoln Bible has been used three times since, by President Barack Obama at each of his inaugurations and by Donald Trump in 2017. In 2013, Obama too took the oath of office keeping his hands on two Bibles — one was owned by Martin Luther King Jr and the other was the Lincoln Bible.
