Full Breakdown
The Stalled Prosecution of the 9/11 Mastermind
By Drooid · · How we work
Core Event
A U.S. military judge has set June 5 2028 as the trial date for Khalid Sheikh Mohammed—the alleged architect of the September 11, 2001 attacks—and three co-defendants. The date follows a series of legal setbacks, including the exclusion of a 2007 FBI confession deemed “tainted” because Mohammed was subjected to “enhanced interrogation techniques” such as waterboarding while in CIA custody. The government has opted not to appeal the ruling, citing concerns that an appeal would further delay any trial.
Background & Context
Mohammed was captured in Pakistan in 2003 and transferred to a series of secret prisons before being moved to Guantanamo Bay. A 2024 plea agreement would have spared the death penalty in exchange for a guilty plea and life imprisonment, but the agreement collapsed after the Department of Defense withdrew in July 2025, arguing that the authority to bind the government rested with the Secretary of Defense.
A U.S. Senate report identified 183 waterboarding sessions and other “enhanced interrogation” methods, which prosecutors argue compromise the admissibility of key evidence.
Timeline
- 2003 – Capture in Pakistan.
- 2006 – Transfer to Guantanamo Bay.
- 2007 – Alleged FBI confession (later ruled inadmissible).
- 2024-07-24 – Plea agreement announced.
- 2025-July – Department of Defense withdraws from plea deal.
- 2028-06-05 – Military judge sets trial date.
Data & Statistics
- 183 waterboarding sessions recorded in the Senate report.
- Three men (Mohammed, Mustafa Ahmed Adam al-Hawsawi, Walid Muhammad Salih Mubarak bin ‘Atash) were slated to plead guilty under the 2024 agreements.
- $3.5 billion in frozen Afghan assets is the subject of a separate Supreme Court petition related to the Terrorism Risk Insurance Act.
Official Statements & Responses
He also described the abandoned plea deal as “a charade in many respects.”
U.S. Solicitor General D. John Sauer urged the Supreme Court to leave the D.C. Circuit’s decision overturning the plea agreements in place, arguing that the death-penalty question should remain with politically accountable officials.
The Department of Defense, through Secretary Lloyd J. Austin III, asserted that ultimate authority over plea agreements rests with the Secretary, justifying the withdrawal.
Criticism & Opposition
Legal scholar David Raskin (formerly slated to lead the government’s prosecution) argued that a civilian trial in New York would likely have produced a conviction, whereas the military commissions have become “a defense lawyer’s dream” plagued by endless procedural disputes.
Conflicting Reports & Gaps
- The plea agreements were reported as “finalized” in July 2024 by some outlets, yet the Department of Defense’s July 2025 withdrawal indicates the agreements were never fully executed.
- The Supreme Court has received three petitions related to the 9/11 prosecutions, but it has not yet indicated whether it will hear arguments; the timing of any decision remains uncertain.
- While the Senate report details 183 waterboarding sessions, the exact impact of those sessions on the admissibility of all evidence remains unsettled, leaving a legal gray area for the upcoming trial.
What’s Next
The Supreme Court is scheduled to consider the petitions concerning the withdrawn plea agreements and the frozen Afghan assets at a conference later this month, with a decision potentially forthcoming in early October. Meanwhile, the June 2028 trial date remains on the docket, though lawyers on both sides caution that further procedural hurdles could push the case beyond that deadline.
