Bill Clinton Has Been Giving Obama Lessons?

Remember "What is the meaning of 'is'?"  4/10/16 CBS New York:

“What I also know, because I handle a lot of classified information, is that there are — there’s classified, and then there’s classified,” Obama told Fox News. “There’s stuff that is really top-secret, top-secret, and there’s stuff that is being presented to the president or the secretary of state, that you might not want on the transom, or going out over the wire, but is basically stuff that you could get in open-source.”

Back when I had a Secret clearance, in the 1970s, I remember how seriously this was treated.  Things have changed?
