Outgoing US President Barack Obama has commuted Chelsea Manning's sentence for leaking documents to Wikileaks in 2010. The 29-year old transgender US Army private, born Bradley Manning, will be freed on 17th May, instead of her scheduled 2045 release. <br/><br/>She was sentenced to 35 years in 2013 for her role in leaking diplomatic cables to the anti-secrecy group. The leak was one of the largest breaches of classified material in US history. The White House had suggested in recent days it was open to commuting Manning's sentence.
