Manning is one of 64 inmates who received pardons from Obama as part of the tradition of outgoing U.S. presidents shortening and commuting the sentences of inmates during their final days in office. Manning is scheduled to be released from Fort Leavenworth on May 17. In 2010, Manning, then an intelligence analyst for the U.S. Army, leaked an enormous batch of classified documents to Julian Assange and Wikileaks that exposed major military and diplomatic activities being conducted by the U.S. government.
