FORT GEORGE G. MEADE, Maryland (CNN) - Defense lawyers for an army private accused in the biggest intelligence leak in U.S. history brought up Saturday an alleged female alter ego of Bradley Manning's as they seek to establish his state of mind at the time of the alleged crimes.
The testimony came on the second day of Manning's Article 32 hearing, which also coincided with his 24th birthday.
A U.S. Army special agent, testifying by phone from Germany, was asked by one of Manning's attorneys if he knew that the Army private had an alter ego with the name, Breanna Manning. The agent said he was aware Manning used the name in online chats.
During questioning by Manning's lawyer, it was revealed Manning kept a folder of articles about gender identity disorder in his living quarters.
Manning is accused of leaking more than a quarter of a million classified Pentagon and State Department documents that ended up on the WikiLeaks website.
