The Supreme Court has rejected an effort to revive a plea deal for Khalid Sheikh Mohammed, the accused mastermind of the September 11 attacks. The deal would have spared him the death penalty in exchange for a guilty plea and life in prison without parole. Military prosecutors and the Pentagon initially approved the agreement, but then-Defense Secretary Lloyd Austin canceled it, saying the defense secretary should decide on the death penalty for such a grave attack. Relatives of the victims are divided on the issue. A trial date has been set for 2028.
