Yes he does.
Why does Burkett claim he's protecting a source he obviously didn't trust in the first place...
Burkett doesn't strike me as someone capable of writing those memos, at least not at this stage of his life. He may have aided in the composition, providing some of the language or providing comments on the contents.
I think the source is someone in the Texas Democrat Committees' organization.
As many others have noted, Rather seemed to have an unusual emotional investment in this story; I'd be looking long and hard at his daughter.
I just had a real conspiracy thought...what if it is dan rather's own democratic activist dtr who is the anonymous giver of secreted documents? LOL I mean...in the article it states that a MAN gave Burkett the documents outside the astrodome in Houston, and now we have a change in story, and it is supposedly a WOMAN, name lucy rameriz or whatever, geeeeeee, this is a WICKED WEB OF DECEIT!
