John Does?

As you have probably heard, at 10:00 AM this morning Joe Wilson and Valerie Plame are holding a news conference to announce that Plame is suing Dick Cheney, Karl Rove, and Scooter Libby over the disclosure of Plame's identity. What you may not have heard is that the suit also names ten John Does who are defined in the suit as:

Defendants John Does No. 1-10 are persons whose identities currently are unknown but who are believed to be persons who were either employed by the United States Government in senior positions at all times relevant to this Complaint or who were political operatives with close ties to such persons.

Mehlmen? Guckert? Inquiring minds want to know.
