In this newly released audio, Private Bradley Manning explains his motives, noting how he believed the WikiLeaks documents showed wrongdoing by the government and how he hoped that the release would "spark a domestic debate on the role of the military and our foreign policy in general as it related to Iraq and Afghanistan."

From Freedom of the Press Foundation:

"Today, Freedom of the Press Foundation is publishing the full, previously unreleased audio recording of Private First Class Bradley Manning’s speech to the military court in Ft. Meade about his motivations for leaking over 700,000 government documents to WikiLeaks. In addition, we have published highlights from Manning’s statement to the court."

"While unofficial transcripts of this statement are available, this marks the first time the American public has heard the actual voice of Manning."
...
"We hope this recording will shed light on one of the most secret court trials in recent history, in which the government is putting on trial a concerned government employee whose only stated goal was to bring attention to what he viewed as serious governmental misconduct and criminal activity. We hope to prompt additional analysis of these proceedings by other journalistic institutions and the public at large. While we are not equipped (technically or as a matter of human resources) to receive leaked information nor do we plan on receiving them in the future, we are proud to publish and analyze this particular recording because it is so clearly matches our mission of supporting transparency journalism."
