The self-proclaimed mastermind of the Sept. 11 attacks is expected to return to the Guantanamo war crimes court, possibly for the last time.

A military judge has scheduled a hearing Monday at the U.S. base in Cuba to ask Khalid Sheikh Mohammed and two co-defendants if they have objections to another delay in their trial at the request of President Barack Obama's administration.

Mohammed is acting as his own lawyer.

Obama has pledged to close the Guantanamo detention center in January. His administration is seeking a 60-day delay to give it more time to decide whether Mohammed and others should be tried in civilian or military courts.
