the latest article of david leonhardt in the "new york times." nancy gibbs, tell me, where are we in this question of truth and how difficult is it for journalists? >> journalists have been debating for a long time about when you say someone is lying, and the challenge there is that it's much easier for us to check facts. we always do that and know this statement is true, this statement is not true, this statement is partially true. when you talk about whether someone is lying, there is an added layer of intent, of what is it that they know and believe? are they mistaken? are they intentionally stating a falsehood? that's where this president has posed a particular challenge to the people covering him. a great many things he says are demonstrably false. but there is the second question of how many things he ss would qualify as lies, he knows what he's saying is false, and how many are things that are actually untrue but he believes are true. i think separating those things is very important because what presidents believe se normsly important in
