This is an expression I call the cry cover smile. Yes, most people who give this expression believe they are covering their true emotions with a smile.
This expression is typically found in men and I think comes from the need to keep a “stiff upper lip.” Many times this expression is an attempt to hide many intense emotions of sadness, fear and anger. I see it in men who typically have very strong egos and power and are caught and brought down. There are several photos of this expression in former Governor Blagojevich.
If I knew exactly when he gave that expression I could tell you whether he was disgusted with himself for what he did or disgusted with the media at a particular question or bringing his behavior to light. The wrinkled, upraised chin and tight lips show the suppression of fear and also of anger.
