This is one statement that has bothered me. Has anyone confirmed this, or are we just taking ER's word for it. She originally said "You know, I`m not sure. I know he`s been asked to" She then said when asked if she knew if he had taken one, " I do not at this time, no." She also said that "No, I don`t think he failed a polygraph. You know, I don`t know the specifics behind that. I don`t think he necessarily failed. But you know, I don`t have any information on that. So it`s real -- it`s real tough for me to answer that question."
When Nancy G asked her if she hadn't told the producers that he had failed a LDT, she said that she'd never said that, and then decided that she knew he had taken one. When pushed, she said she believed was inconclusive.
That's been the basis for all of the "knowledge" about him failing a LDT or his results being inconclusive.
