关于总统在宣誓时是否手按《圣经》:
Use of Bibles[edit]
By convention, incoming Presidents raise their right hand and place the left on a Bible or other book while taking the oath of office. In 1789, George Washington took the oath of office with an altar Bible borrowed from the St. John's Lodge No. 1, Ancient York Masons lodge in New York, and he kissed the Bible afterward.[17][18] Subsequent presidents up to and including Harry Truman, followed suit.[19] Dwight Eisenhower broke that tradition in 1953 when he said a prayer instead of kissing the Bible.[20]
Theodore Roosevelt did not use a Bible when taking the oath in 1901.[21] Both John Quincy Adams and Franklin Pierce [22] swore on a book of law, with the intention that they were swearing on the constitution.[23] Lyndon B. Johnson was sworn in on a Roman Catholic missal on Air Force One.[24] Harry Truman, Dwight Eisenhower, Richard Nixon, George H. W. Bush, Barack Obama and Donald Trump each swore the oath on two Bibles.[21]
