From Power Line, in an item also called "Modified Limited Hangout" (file under Great Minds Think Alike):
"Yesterday you stated that CBS originally approached Burkett for the story, that Burkett did not seek you out. Who directed you to Burkett? Was it a member of the Kerry campaign? Why have you not identified the name of the person who directed you to Burkett?
"Did any member of the Kerry campaign have a hand in the story? Did the campaign direct you to any of the 'unimpeachable sources' you used for the story? What members of the Kerry campaign did CBS speak with about the story before it aired? Is it a sheer coincidence that the Kerry campaign unrolled its 'Operation Fortunate Son' attacking President Bush's Air National Guard service the same week that you broadcast the 60 Minutes story?
"The answers to these basic questions are within your knowledge. Will you please answer them publicly now? Why not?"
