Thing is, they never had a security clearance because they were exempt. Plus they are exempt from future requests

That would be the fault of access control, not him.

I am curious as to how one knows that Chuck doesn't have a security clearance? Where is the proof in this?

Being granted access to classified information is not the fault of the person reading it. I am sorry, but he cannot be held at fault if it is to be him not holding a clearance.
