Four years ago, the president took the oath on the Lincoln Bible, the first President since Lincoln back in 1861. And he’ll use it again this year. The big parade and inauguration extravaganza will be on Monday, because January 20 falls on a Sunday. This means the president will take the official oath on Sunday, and he’ll use the family Bible given to him by the First Lady’s family. When the whole gang gets together on Monday, the president will also haul out Martin Luther King’s bible.
