Former US Army intelligence analyst Chelsea Manning will remain in jail after a federal appeals court denied her request to be released on bail.
The court upheld a lower court's decision to hold Manning in civil contempt for refusing to testify before a grand jury.
Monday's ruling is a blow to Manning, who has been detained since March after she declined to answer questions in connection with the government's long-running investigation into WikiLeaks and its founder Julian Assange.
Manning said that while disappointing, the appeals court ruling will still allow her to "raise issues as the government continues to abuse the grand jury process".
"I don't have anything to contribute to this, or any other grand jury," Manning said in a comment released by a spokesman.
Assange was arrested on April 11 at Ecuador's Embassy in London, after US prosecutors unsealed a criminal case against him alleging he conspired with Manning to commit computer intrusion.
The Justice Department said Assange was arrested under an extradition treaty between the United States and Britain.
The US government alleges Assange tried to help Manning gain access to a government computer as part of a 2010 leak by WikiLeaks of hundreds of thousands of US military reports about the wars in Afghanistan and Iraq and American diplomatic communications.
Manning was convicted by court-martial in 2013 of espionage and other offences for furnishing more than 700,000 documents, videos, diplomatic cables and battlefield accounts to WikiLeaks while she was an intelligence analyst in Iraq.
Former president Barack Obama commuted the final 28 years of Manning's 35-year sentence.
Manning has tried to fight the grand jury subpoena in the Assange case, citing her first, fourth and sixth Amendment rights under the constitution.
