US blocks plea deal with accused 9/11 mastermind and architect of terrorist attacks

The Biden administration has temporarily blocked Khalid Sheikh Mohammed's guilty plea deal for the 9/11 attacks after a federal appeals court granted a stay. Mohammed, 59, was set to plead guilty in exchange for a prison sentence at Guantanamo Bay, but the U.S. government argued that accepting the plea would cause irreparable harm. Defense lawyers criticized the move as part of two decades of case mishandling by the military and past administrations.
