The latest snag for a Military Tribunal at Guantanamo Bay is over the screening of detainee mail.

FOX News Radio's Lisa Brady reports as part of our ongoing series on National Security:

Securing America:

Now we know what led to the recent change by the Guantanamo Prison Commander who ordered a security review of all legal correspondence between detainees and their attorneys. The directive was given after a copy of Al-Qaeda's english language magazine was found in a terror suspect's cell. Defense Attorneys say screenings violate attorney-client privilege, and the issue is front and center at pre-trial hearings this week for a suspected senior Al-Qaeda leader accused of orchestrating the deadly attack on the USS Cole. The Military Judge for that case, telling both sides to submit their proposals, on how to handle the mail.
