US Supreme Court rejects 9/11 mastermind's bid to revive plea deal

The US Supreme Court declined to hear Khalid Sheikh Mohammed's appeal to reinstate plea agreements that would have spared him the death penalty. The lower court had ruled the plea deals were invalidly approved by a military official, and the rejection finalizes that decision. This removes a potential legal resolution for the long-running 9/11 case, leaving the trial process to continue.
