Manning will remain in prison until the grand jury concludes its investigation or the former analyst agrees to testify, according to The AP.
In 2013, she was sentenced to 35 years in prison. Chelsea has stood by the testimony from her 2013 court-martial, and this subpoena serves no legitimate objective.
Manning announced she had received an order to give evidence in front of a grand jury. "I will exhaust every legal remedy available", said Manning.
Reaction to Manning's imprisonment from supporters praised the whistleblower's courage and her commitment to her principles while condemning the government for detaining Manning. Grand juries are notoriously mired in secrecy, and have historically been used to silence and retaliate against political activists.
What's more, other reports suggest WikiLeaks may have also solicited cyberattacks against a United States ally overseas, which was definitely a branch of DOJ's long-running investigation into the organisation, as evident by the involvement of FBI agents and informants.
Manning's attorney, Moira Meltzer-Cohen, said it would be "an act of tremendous cruelty" to her to jail, but did thank prosecutors who "bent over backwards to accommodate" medical needs linked to Manning's gender reassignment. "We hope she changes her mind now", McCormick said, according to CBS.

As Law&Crime noted before, Manning was subpoenaed by the U.S. Attorney for the Eastern District of Virginia, which is the same office that mistakenly revealed that there might be a criminal case there against WikiLeaks founder Julian Assange.
McCormick said Manning could easily end this incarceration on the civil charge simply by following the law and testifying.
Wikileaks has emerged as an important part of Special Counsel Robert Mueller's investigation into possible Russian meddling into the 2016 presidential election, as investigators focus on whether President Donald Trump's campaign knew Russian hackers were going to provide emails to Wikileaks stolen from Democratic organisations, including presidential candidate Hillary Clinton's campaign.
After journalists discovered the document, prosecutors declined to either confirm or deny a sealed indictment had been issued by the Alexandria-based grand jury, which has been hearing evidence on Assange and Wikileaks for years.
