ONYX covered the Guantánamo 9/11 trial’s 2028 scheduling on August 29: the 27-year timeline from attack to trial; prosecutors younger than the case; the 2028 date’s uncertainty given prior postponements. Today’s pretrial developments.

THE PRETRIAL STATUS  

The Guantánamo military commission handling the case of Khalid Sheikh Mohammed and four co-defendants is in ongoing pretrial proceedings. The 2028 trial date is the scheduled target; pretrial motions — on classified information, evidence admissibility, and defense access to witnesses — continue to generate the procedural record that the trial will draw on. Today’s specific pretrial development is from confirmed reporting; ONYX covers it at the level of confirmed facts without speculation about the trial’s ultimate outcome.

The specific ongoing challenge in pretrial proceedings: classified information management. The defendants’ knowledge of CIA black site locations and interrogation methods — from their years of pre-Guantánamo detention — creates a classified information problem that has generated years of litigation about what the defense can access, what evidence the prosecution can present, and how the trial can be conducted without compromising intelligence sources and methods.

Twenty-five years after September 11. Three years before the currently scheduled trial. The classified information problem that has delayed this case since 2006 is still unresolved. The families of the 2,977 people who died on September 11 have been waiting for a trial since 2002.

CONFIDENCE: HIGH

Guantánamo 9/11 trial 2028 target, pretrial proceedings, classified information challenge are from confirmed reporting and ONYX August 29 documentation.
