National security leaker Chelsea Manning is appealing her 2013 court-martial conviction for sending classified material to the anti-secrecy website WikiLeaks while serving as an Army intelligence analyst in Iraq.
Manning attorney Vincent Ward says the documents were filed Wednesday with the U.S. Army Court of Criminal Appeals at Fort Belvoir, Virginia.
Chief Deputy Clerk John Taitt says the document must undergo a review for classified information before it can be publicly released.
Ward says he'll wait until the review is complete before commenting.
Manning is serving a 35-year sentence at Fort Leavenworth, Kansas. The transgender soldier, formerly known as Bradley Manning, was convicted of espionage and other offenses for sending WikiLeaks more than 700,000 digital files including battlefield logs, diplomatic cables and video clips.
