The military trial of accused Army whisleblower Bradley Manning has been postponed until June to weigh a prosecution request to use classified information as evidence against him. On Wednesday, prosecutors said they will introduce evidence that shows Osama bin Laden sought out and received some of the U.S. government cables that Manning is accused of having released to WikiLeaks. Prosecutors also say they will present transcripts of an online chat between Manning and WikiLeaks founder Julian Assange. On Wednesday, Manning’s attorneys renewed their offer for him to plead guilty to passing on the documents to WikiLeaks if the government drops charges of espionage and aiding the enemy. Manning’s offer would subject him to a sentence of up to 20 years instead of the life term he faces behind bars.
