In Kansas, imprisoned Army whistleblower Chelsea Manning walked free from Fort Leavenworth prison this morning, after spending seven years behind bars for leaking more than 700,000 classified files and videos to WikiLeaks about U.S. foreign policy and the wars in Iraq and Afghanistan. Manning was sentenced to 35 years in prison in 2013 after she was convicted under the World War I-era Espionage Act. In January, President Obama commuted her sentence shortly before leaving office. Manning is already the longest-held whistleblower in U.S. history.
