Investigative documents in the WikiLeaks probe spilled out into the public domain Saturday for the first time, pointing to the Obama administration's determination to assemble a criminal case no matter how long it takes and how far afield authorities have to go.

Backed by a magistrate judge's court order from Dec. 14, the newly disclosed documents sent to Twitter Inc. by the U.S. attorney's office in Alexandria, Va., demand details about the accounts of WikiLeaks founder Julian Assange and Pfc. Bradley Manning, the Army intelligence analyst who's in custody and suspected of supplying WikiLeaks with classified information.

The others whose Twitter accounts are targeted in the prosecutors' demand are Birgitta Jonsdottir, an Icelandic parliamentarian and one-time WikiLeaks collaborator; Dutch hacker Rop Gonggrijp; and U.S. programmer Jacob Appelbaum. Gonggrijp and Appelbaum have worked with WikiLeaks in the past.

Justice Department spokesman Matt Miller declined comment on the disclosure in the case, which intensified following WikiLeaks' latest round of revelations with the posting of classified State Department diplomatic cables. The next day, Nov. 29, Attorney General Eric Holder vowed that anyone found to have violated U.S. law in the leaks would be prosecuted.
