how things appear in the world of politics obviously there is the optics how this would appear if the white house requested that comey not testify because of executive privilege it would also probably look like the president was trying to hide something. >> that's exactly right, anderson. and it's one of the reasons i made the argument that the particular selection of the lawyer mark kass wits from new york who is not a criminal defense lawyer was why the white house did that was because of the optics of it. i don't think there is any chance what so far that they're going to go in and try and seek to prevent him wholesale from testifying. what they're going to do is try and surgically, laser like precision hopefully -- if i understand what they're going to do -- tell him this area you can you this dwrar you can't. the one thing we haven't discussed is -- the one area this privilege where there is an argument that it gives sway is in a criminal context.
