“Early yesterday morning, I received serious charges in relation to my suicide attempt earlier this month,” Manning’s account tweeted Friday.
If she is found guilty, Manning could lose her chance at parole and face decades in solitary confinement, according to an American Civil Liberties Union press release.
“It is deeply troubling that Chelsea is now being subjected to an investigation and possible punishment for her attempt to take her life,” ACLU staff attorney Chase Strangio said.
“While Chelsea is suffering the darkest depression she has experienced since her arrest, the government is taking actions to punish her for that pain.”
A transcript of the Army’s notice of investigation— dictated by Manning in a phone call — didn’t specifically mention the failed June 5 suicide attempt.
After trying to end her life, Manning was briefly taken to a local hospital.
The 28-year-old is serving a 35-year sentence in a Kansas military prison after a 2013 conviction for espionage. Manning leaked thousands of State Department files through Wikileaks during her time in the military.
Born Bradley Edward Manning, came out as transgender shortly after her conviction. She started hormone treatment in prison in 2015.
Since she was taken into custody in 2010, the erstwhile intelligence analyst has served her entire sentence in an all-male prison.
In May, Manning filed an appeal for her espionage conviction.
