James Connell says he was able to see the camp and meet there for the first time with his client, Ammar al-Baluchi.
Connell says that he can't yet reveal what he saw but that he does not believe conditions meet Geneva Conventions standards.
A judge granted Connell and two experts 12 hours to view the camp and meet with al-Baluchi. The lawyer had never before seen the inside of Camp 7, which is so shrouded in secrecy that its location on the US base in Cuba is classified.
