WP: "Khalid Sheik Mohammed, the self-proclaimed operational mastermind of the Sept. 11, 2001, terrorist attacks, and four co-defendants told a U.S. military court in Guantanamo Bay, Cuba, Monday that they want to make a "confession" and enter guilty pleas to murder and war-crimes charges in the death-penalty case. The startling announcement came at the start of what was supposed to be a week of pre-trial hearings on various motions. It could create a major dilemma for the incoming administration of President-elect Barack Obama, who has said he wants to close the Guantanamo detention facility and prosecute defendants such as Mohammed in federal courts."
