do you have to swear on the bible to be president
Theodore Roosevelt did not use a Bible when taking the oath in 1901. Both John Quincy Adams and Franklin Pierce swore on a book of law, with the intention that they were swearing on the constitution. Lyndon B. Johnson was sworn in on a Roman Catholic missal on Air Force One. Harry Truman, Dwight Eisenhower, Richard Nixon, George H.W. Bush, Barack Obama and Donald Trump each swore the oath on two Bibles.
