Biden Administration Asks Court To Block Plea Deal For Alleged Mastermind Of 9/11 Attacks

The Biden administration asked a federal appeals court on Tuesday to block a plea agreement for accused 9/11 mastermind Khalid Sheikh Mohammed that would spare him the risk of the death penalty in one of the deadliest attacks ever on the United States.

The Justice Department argued in a brief filed with a federal appeals court in the District of Columbia that the government would be irreparably harmed if the guilty pleas were accepted for Mohammed and two co-defendants in the Sept. 11, 2001, attacks.

It said the government would be denied a chance for a public trial and the opportunity to 'seek capital punishment against three men charged with a heinous act of mass murder that caused the death of thousands of people and shocked the nation and the world."

The Defense Department negotiated and approved the plea deal but later repudiated it. Attorneys for the defendants argue the deal is already legally in effect and that Defense Secretary Lloyd Austin, who began the administration's efforts to throw it out, acted too late.

When the appeal was filed Tuesday, family members of some the nearly 3,000 people killed in the al-Qaida attacks already were gathered at the U.S. naval base in Guantanamo Bay, Cuba, to hear Mohammed's scheduled guilty plea Friday. The other two men, accused of lesser roles in 9/11, were due to enter them next week.
