Chelsea has been incarcerated since May 2010, which means that at the time of her request for commutation, in November, 2016, she had been in custody for over 6 1/2 years.
Of that time, 11 months were spent in unusually harsh conditions of solitary confinement, which the UN considers to be a form of torture. The UN special rapporteur on torture formally accused the US government of cruel, inhuman and degrading treatment towards Chelsea during this period of isolation.
