9/11 Mastermind's Trial Delayed to June 2028 as Legal Disputes Persist
The case will proceed to trial, where execution remains possible.
Why has it taken so long to get this case to trial? We're talking about events from 2001.
The short answer is that military commissions are slow, and this case involves questions about evidence that the government obtained through interrogation methods that are now legally contested. Every piece of evidence has to be fought over.
So the judge is saying they need eighteen more months just to figure out what can be presented?
Essentially, yes. There are disagreements about what's admissible, what was obtained legally, what violates the rules of evidence. These aren't small questions—they go to the heart of how the case was built.
I read that a plea deal fell apart last year. What happened there?
Mohammed had agreed to plead guilty, which would have ended the case without a trial. But a federal appeals court threw it out. So now instead of a guilty plea, there will be a full trial with all the risks that entails—including the possibility of execution.
That's a significant reversal. Why did the court reject the plea?
The ruling didn't elaborate on the reasoning in the reporting, but the effect is clear: the case is now headed toward a full adversarial trial rather than a negotiated resolution.
And even with this June 2028 date, there's no guarantee it will actually happen?
That's right. The judge made it contingent on meeting deadlines. A trial was scheduled for 2021 and cancelled. This date could slip again if new disputes arise or deadlines aren't met.
El Pulso
- A U.S. military judge has pushed the 9/11 trial to June 5, 2028 — eighteen months later than prosecutors demanded — citing unresolved disputes over what evidence will even be permitted in the courtroom.
- Khalid Sheikh Mohammed and three alleged co-conspirators remain held at Guantanamo Bay, their legal fate suspended after a federal appeals court last year invalidated a plea deal that would have taken execution off the table.
- The case has now spent more than two decades in the military justice system without reaching trial, with a previously scheduled 2021 date having already collapsed under the weight of procedural complications.
- Even the 2028 date is not guaranteed — the judge's order ties it explicitly to the meeting of legal deadlines, leaving open the possibility of yet another postponement if new disputes arise.
- For the families of the nearly 3,000 people killed on September 11, 2001, each delay extends a wait for closure that has already outlasted many of their expectations.
More than two decades after nearly 3,000 lives were lost on a single September morning, the man accused of architecting that catastrophe still has not faced a jury. A U.S. military judge has now set June 2028 as the trial date for Khalid Sheikh Mohammed and three co-defendants — eighteen months beyond what prosecutors sought — a delay that speaks not to indifference but to the profound difficulty of delivering justice in a case of extraordinary legal, moral, and historical weight. The slow turning of this proceeding reminds us that accountability, when pursued through the rule of law, is rarely swift, and that the distance between an act of mass violence and its legal reckoning can span a generation.
On August 26, 2026, a U.S. military judge announced that the trial of Khalid Sheikh Mohammed and three co-defendants would begin on June 5, 2028 — a date eighteen months beyond what prosecutors had requested. Air Force Lt Col Michael A Schrama determined that the additional time was necessary to resolve deep pretrial disputes, particularly over what evidence would be admissible at trial. The decision reflects the staggering complexity of a case that has spent more than two decades in the military justice system without ever reaching a courtroom.
Mohammed is accused of conceiving and directing the plot that turned commercial airliners into weapons on September 11, 2001, killing nearly 3,000 people across the World Trade Center, the Pentagon, and a field near Shanksville, Pennsylvania. He will stand trial alongside Walid bin Attash, Ali Abdul Aziz Ali, and Mustafa al-Hawsawi — all four still detained at Guantanamo Bay among its dwindling population of remaining prisoners.
The road to 2028 is already scarred by false starts. A trial once set for 2021 was cancelled entirely. The current date comes with no guarantee either, contingent as it is on the case clearing every legal milestone ahead. Complicating matters further, a federal appeals court last year struck down a plea agreement that would have allowed Mohammed to plead guilty in exchange for avoiding the death penalty — meaning the case will now proceed to full trial with execution still a possible outcome.
What was once imagined as a defining moment of post-9/11 justice has instead become one of the longest and most procedurally tortured prosecutions in American legal history, a slow reckoning still searching for its conclusion.
On Wednesday, August 26, 2026, a U.S. military judge announced that the trial of Khalid Sheikh Mohammed and three co-defendants would begin on June 5, 2028. The date represents a significant delay from what prosecutors had sought—they had asked for the trial to start in January 2027, but the judge determined that an additional eighteen months was necessary to work through the legal tangles that have accumulated around the case.
The core dispute centers on what evidence will be allowed into the courtroom. These pretrial disagreements have proven substantial enough that the judge, Air Force Lt Col Michael A Schrama, concluded they could not be resolved in time for the earlier date. The decision reflects the extraordinary complexity of prosecuting a case that has been in the military justice system for more than two decades without reaching trial.
Mohammed stands accused of developing and directing the plot to hijack commercial airliners and crash them into the World Trade Center and the Pentagon on September 11, 2001. A fourth plane, also hijacked as part of the same operation, went down in a field near Shanksville, Pennsylvania. He will face trial alongside three alleged accomplices: Walid bin Attash, Ali Abdul Aziz Ali, and Mustafa al-Hawsawi. All four remain detained at the U.S. military detention facility at Guantanamo Bay, Cuba, among the last prisoners still held there.
The path to this June 2028 date has been anything but straightforward. A trial was previously scheduled for 2021 but was ultimately cancelled. Even the current date carries no guarantee of finality—the judge's order makes clear that the trial is contingent on the case meeting all legal deadlines and milestones along the way. Should disputes continue to mount or new complications emerge, another postponement remains possible.
The case has been further complicated by a dramatic reversal in the legal landscape. Last year, a federal appeals court threw out a plea agreement that would have allowed Mohammed to plead guilty. That deal would have spared him the possibility of execution for his role in the attacks that killed nearly 3,000 people. The rejection of the plea agreement means the case will now proceed to a full trial, where the death penalty remains a potential outcome.
The extended timeline underscores the institutional challenge the U.S. military and successive administrations have faced in bringing to justice the man widely regarded as the principal architect of one of the deadliest attacks ever carried out on American soil. What was once expected to be a relatively swift process has instead become a slow, grinding legal proceeding marked by procedural disputes, strategic reversals, and the sheer difficulty of managing a case of this magnitude and sensitivity within the military justice system.
