Defense arguing military ignored signs of mental stress

U.S. Army Private First Class Bradley Manning, convicted of providing a massive trove of secret files to WikiLeaks in the biggest data breach in U.S. history, could break a long silence on Wednesday as the sentencing phase of his court-martial ends.

Manning, 25, faces up to 90 years in prison for providing more than 700,000 documents, battle videos and diplomatic cables to WikiLeaks, hurling the pro-transparency website and its founder, Julian Assange, into the world spotlight.
