If memory serves me right that is a quotation from Matt Drudge and no one else.  Matt was also the one who floated the bogus report about an internal "investigation" at CBS had Rather "shell-shocked".   When one reporter asked Rather about how the "investigation" made him feel Rather demanded several times to know where she had read that and of course she was unwilling to say Matt Drudge© on camera.  But he was the only one to report that too.  But it was clear the Rather had seen Drudge because he expanded his denial by saying something to the effect that "I feel confident and fine, if anyone is acting shell-shocked it is the people objecting to this." 

This claim of Drudge that he has a mole inside CBS who knows all about Rather's mental state and the discussions among the producers working with Rather must have gotten Rather's goat.

But remember when a British wag was asked what he was going to do about some bad press and said "I don't pick fights with people who buy their ink by the barrel."  I think the Bushies should think twice before picking this sort of a fight with some who controls as much free media as Rather can.  Already the flap about the type font and its pickup by the other outlets has given Rather not just an excuse to air everyting again in a regular news program but almost required him to demand that Bush himself respond to the question raised by the 60 Min. report.
