Attorney General Michael Mukasey is getting his first look at the U.S. detention center at Guantanamo Bay, Cuba.

A Justice Department spokesman says the attorney general arrived Wednesday morning and is expected to spend about six hours at the Naval station.

Peter Carr says the visit will give Mukasey a chance to see first hand the detention facility and to sit down with officials who are involved in military commission hearings for suspected terrorists.

Justice Department prosecutors have been helping the government's case against Al Qaeda lieutenant Khalid Sheik Mohammed and other so-called high value detainees held at Guantanamo Bay.
