I don't see where an agent talking to a friend about what kind of person a President, Vice Pres., their spouse is has anything to do with security. I've provide security (not on the scale of the Secret Service though, that I really didn't like but still did my job to the max. It's the same with the SS agents they do their job regardless. So get off of it will you!
So you don't think it's necessary for the protectees to be secure that their actions and conversations will be held in confidence by those protecting them?
