Talking about public business
There’s a phrase that gets bandied about occasionally by public officials when asked by reporters for comment about a particular matter. It’s meant as a conversation stopper; a statement against which no reasonable person could or would argue because it is meant to convey a certainty, as steadfast and unassailable as a the gaze of the Sphinx.
There are several versions of the phrase, but essentially it goes like this:
“I can’t comment on something we discussed in closed session.”
