I saw the 60 Minutes episode. Knox said she didn't type the memos, but the information contained was correct. She spoke of memos and notes that Killian (sp?) kept locked away.
After it was all said and done, Rather stated that if the documents were indeed forgeries, they would report it, BUT... Bush's preferential treatment entering the Guard and his dereliction of duty was an important story and they would continue to report.
It's not important. It's not relevant. The president is coming up on four years in office. It's a little late to question his character of thirty years ago. What difference does it make?
