A verdict is expected today in the court-martial of Army whistleblower Bradley Manning for the largest leak of classified information in U.S. history. Manning faces up to life in prison for the most serious of the more than 20 charges against him — aiding the enemy — after he leaked more than 700,000 documents to WikiLeaks in an attempt to spark a national debate about U.S. foreign policy. He has pleaded guilty to 10 of the charges which could carry up to 20 years in prison. After nearly two months of trial at Fort Meade, Maryland, the judge, Colonel Denise Lind, said she plans to announce her verdict at 1 p.m. Eastern time today. After the verdict, the trial enters the sentencing phase where both the prosecution and defense will present more evidence and arguments.
