usually when you get this kind of leak there is some level of decent within a team. i would assume within the defense team. to me it's kind of a contradiction at the heart of this. the argument from the lawyer seems to be that the president cannot obstruct justice, cannot obstruct an investigation because his power over federal investigations is virtually unlimited. that would be news to the house of representatives in 1974 whose articles one and two referenced obstruction of justice. it may be some what secondary.
