Military prosecutors have finished laying out their case against alleged Army whistleblower Private Bradley Manning in a pretrial military hearing to determine whether he is to face a court-martial for leaking classified videos and diplomatic cables to WikiLeaks. The first defense witnesses are expected to testify today. On Tuesday, the man who turned Manning in to U.S. authorities, Adrian Lamo, denied in his testimony that he had violated a journalistic or ministerial promise of confidentiality when he handed over the chat logs that led to Manning’s arrest.
