Question mark?

I wonder if the use of the question mark after the chairman's response was correct.  or was he asking Andrew Parker if Hazel Blears is one of those threats?

ANDREW PARKER: ... The work we do is addressing directly threats to this country, to our way of life, to this country and to people who live here; and the work we do is proportionately judged against the necessity of protecting against those threats. 

CHAIRMAN: Hazel Blears?
