officials, you know, a lot of those folks are people who the white house has direct access to. there's no question for example that the white house is going to have ongoing access to and communications with people like hope hicks or jared kushner or donald trump jr., people like that are not going to tell investigators anything that's going to surprise the white house, because those folks are in the white house every day. but then there's steve bannon. who ran the president's campaign. he's in a position to know a lot of really high-level insider information about a number of things we believe the mueller investigation is looking at. the white house doesn't know that what steve bannon's going to say. they don't necessarily know what he knows, what he's inclined to talk about, what he would like to talk about. >> former white house chief strategist steve bannon testified yesterday. didn't answer a lot of questions. refused to answer some before the intelligence committee.
