Advocates of a transgender soldier imprisoned for sending classified information to an anti-secrecy website say they've collected more than 115,000 petition signatures protesting new charges she faces related to her recent suicide attempt.

Activist groups including Demand Progress presented the petitions Wednesday to Secretary of the Army Eric Fanning's office on Chelsea Manning's behalf.

Manning was convicted in 2013 in military court of Espionage Act violations and other offenses for giving secret military and State Department documents to WikiLeaks. Manning was an intelligence analyst in Iraq at the time.

Manning has been imprisoned at Kansas' Fort Leavenworth and tried to kill herself July 5. The ACLU says she now faces administrative charges related to it, and possible punishment could include indefinite solitary confinement.
