The father of accused whistleblower U.S. Army Private Bradley Manning has spoken out for the first time since Manning was arrested for allegedly leaking classified information to WikiLeaks. Since June, Manning has been held in solitary confinement on a Marine brig in Virginia. In an interview with PBS Frontline, Brian Manning said he was shocked by the conditions under which his son was being held.

Brian Manning: “I mean this is someone that has not gone to trial or been convicted of anything. And that’s prompted me to come out and go forward. They worry about people down in a base in Cuba, but here they are, have someone at a base on our own soil, under their own control, and they’re treating him this way. You just can’t believe. It’s shocking enough that I would come out of our silence as a family and say, ‘Now then, you’ve crossed the line. This is wrong.’”
