US soldier Chelsea Manning has been released from prison after serving seven years for leaking hundreds of thousands of diplomatic cables and military files to Wikileaks.
A US Army spokesperson confirmed to the BBC that she had left Fort Leavenworth military prison in Kansas.
Most of what remained of her 35-year sentence was commuted by then-US President Barack Obama in January.
Her lawyer earlier said she was excited but likely to be “anxious”.
“She’s ready to finally be able to live as the woman that she is,” Nancy Hollander told the BBC. The 29-year-old soldier was born Bradley Manning.
A day after she was sentenced to 35 years in prison in 2013, Manning said she had felt female since childhood and wanted to live as a woman called Chelsea.
“For the first time, I can see a future for myself as Chelsea,” she said in a statement last week ahead of her release. “I can imagine surviving and living as the person who I am and can finally be in the outside world.”
Speaking to the BBC, Manning’s friend, the journalist Glenn Greenwald – who was involved in the publication of leaks from Edward Snowden – said she faced a difficult life outside of prison.
“She’s going to live in a country where the top officials have expressed extreme denunciations of her, condemnations of her, who regard her as a traitor,” he said.
“But the reality is that if you look back at what it is that she achieved, she revealed unquestionable war crimes, her disclosures led to reforms around the world.”
President Obama’s decision to commute her sentence drew criticism from leading Republicans, including Senator John McCain, who called it a “a grave mistake”.
