“You want my opinion? My opinion is that you’re not very good at your job and your boss should send someone else to do this. If you want to know about what they said, go ask them. If you’d like to talk to me about the issues or anything I said, feel free. Next question.” [emphasis in originial]
Read it all. It makes perfect sense, to demand better from these reporters. And it works! I remember listening to Margaret Thatcher as she did this to an NPR reporter back around the time of the Falklands War. Very quickly the reporter got focused on asking intelligent questions, and the interview for Thatcher turned out to be resounding success.
