there is a sort of policy in place by which typically security clearance are considered to be revoked. a wrote a piece last week. there are 13 ways and reasons by which they are typically revoked, mental stability is one, alcohol or drug abuse or suspected drug abuse. those are the usual reasons. disagreeing politically -- this is in regards to john brennan -- is not one. not being friendly enough to the administration as kellyanne conway said john brennan wasn't is not one. i do think when you are sort of dangling it in front of people -- that's not what the revocation process is supposed to look like. >> the president also dangled the status of robert mueller's own clearance in addition to there was an article talking about that revoking clearances is something that has been talked about 17 months ago.
