In a CBS interview Hillary says that she always "tried" to tell the truth to the American people, thereby leaving open the possibility that she knowingly lies to the American people. This is done in the context of her interview in which the interviewer presses her on whether she always tells the truth. She cannot say she does, just that she "tries" to.
