Barbara Walters Not Cool with Politicians Swearing Oath of Office on Bible Barbara Walters on "The View" Thursday morning: "That is very true, but it starts almost with the oath of office which usually ends with, 'So help me God.' Now, most presidents swear on a Bible before taking office, even though we have the separation between church and state. You see it again and again. You don’t have to use a Bible. Teddy Roosevelt didn’t. John Quincy Adams swore on a law book and Lyndon Johnson took the oath on a book he thought was the Bible. We don’t know what the book was... We talk about the separation between church and state and almost every president ends up saying, 'so help me God.'"
