Former Army intelligence analyst Chelsea Manning says she'll stay in jail "forever" rather than testify to a grand jury investigating Wikileaks.

Manning spoke to reporters Thursday afternoon outside the federal courthouse in Alexandria before a scheduled hearing.

She faces possible jail on civil contempt for refusing to obey a grand jury subpoena. She already spent two months in jail on a previous subpoena but was released last week when the term of that grand jury expired.

Manning argues that she should not be sent to jail because she has already demonstrated that incarceration won't coerce her into testifying. She served seven years in a military prison for leaking a trove of documents to WikiLeaks before then-President Barack Obama commuted the remainder of her 35-year sentence.
