>> joining me now is our white house correspondent, kristen welker and hallie jackson, who has been covering donald trump, joining us from the white house. you know full well what president obama's hopes are. i want to ask hallie what donald trump is hoping for out of this meeting. but, kristen, first to you. >> reporter: president obama wants to set the tone, andrea. he wants to set the tone for a smooth transition. i'm told he wants to answer lots of questions. he's likely going to talk about the difference between campaigning and governing and the challenges with making that type of a transition. i'm told this is not going to be a moment for him to go into lecture mode. we know he is good at that. he is known for that. but that is not what this moment is going to be about. this is about talking about policy, answering donald trump's questions, and moving forward. one white house official telling me the mood here at the white house among staffers is bleak. president obama called a number of them into his office yesterday.
