Supreme Court Rejects Attempt to Revive 9/11 Mastermind Plea Deal
Tap title to read story
The Supreme Court on Monday rejected an appeal by Khalid Sheikh Mohammed and two other alleged 9/11 plotters seeking to enforce a plea deal. The men had agreed to life sentences in a 2024 deal signed by a military commission judge. Days later, then-Defense Secretary Lloyd Austin rejected the proposal, claiming authority to override it. Military courts said Austin had no such power, and an August ruling by the U.S. Court of Appeals for the District of Columbia Circuit favored the government. The Supreme Court’s decision removes a barrier to Mohammed’s trial before a military commission in 2028, where the death penalty is possible. Mohammed has been held at Guantanamo Bay, Cuba, since 2006.
