WASHINGTON – 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.
