CBS is having a hard time figuring out where they got the memos from. There's a lot of speculation flying around, but this from the America Spectator was interesting.

MEANWHILE, OVER THE WEEKEND journalists from around the country were attempting to track down the original source of the documents. "We're having a hard time tracking how we got the documents," says the CBS News producer. "There are at least two people in this building who have insisted we got copies of these memos from the Kerry campaign by way of an additional source. We do not have the originals, and our sources have indicated to us that we will not be getting the originals. How that is possible I don't know."

I think is possible because, as Glenn Reynolds put it, CBS was scammed.
