Representative Dennis Kucinich is asking this question, and considering the extended isolation, the enforced nudity, etc. He’s right.
What is particularly telling is the fact that he has asked to speak to Manning, and it’s being deliberately slow walked.
That being said, Kucinich is being far to circumspect in his statement. It is clear that this behavior has been authorized at the very highest levels, and Barack Obama needs to be named, and shamed, over this.
