Snapping on Ed Henry

It's probably not going to be a good night for your news agency when the President thumps your correspondent's follow-up question.  But such is the life of CNN and Ed Henry tonight, whose attempt at gotcha regarding AIG received the response of the evening (video to follow): "I like to know what I'm talking about before I speak."  

Bonus points for using "to talk" and "to speak" in the same sentence.  It's the kind of grammatical formulation that will be helpful for those learning English from the President's speeches.
