What makes you think the people making it don't care? What if they were making the comment to an American agent? Or doesn't that matter to you either?
Shocking! There isn't much that isn't Classified in DC! Both sides have released information. Hell it was just a few months ago when Republicans made TV appearences and released classified data. It happens on both sides.
However this is a minor leak. The VP is trying to head this off before it gets out of control. That is what this is all about. In my humble opinion.
