A man in the CIA used as a guinea pig for its post-9/11 torture program will please his case for freedom from Guantanamo Bay later this month, the Pentagon announced. Zayn al-Ibidin Muhammed Husayn, better known as Abu Zubaydah, is one of three men the CIA acknowledged that it waterboarded. Karen Greenberg noted that the decision to permit Abu Zubaydah a hearing represented a boldness by the White House in its internal and congressional battles over closing Guantanamo. "Abu Zubaydah is at the heart of everything that keeps Gitmo from closing: the issue of torture." Greenberg said.
