This is news to me. The Kerry campaign admits it was the source of these docs?!! Where did you hear or see this statement?

From the The American Spectator's "Washington Prowler" yesterday:
"More than a couple people heard about the papers," says the DNC staffer. "I've heard that they ended up with the Kerry campaign, for them to decide to how to proceed, and presumably they were handed over to 60 Minutes, which used them the other night. But I know this much. When there was discussion here, there were doubts raised about their authenticity."
The concerns arose from the sourcing. "It wasn't clear that our source for the documents would have had access to them. Our person couldn't confirm from what file, from what original source they came from."
