Military judge sets June 2028 trial date for 9/11 mastermind Khalid Sheikh Mohammed

A U.S. military judge has set a trial date of June 5, 2028, for Khalid Sheikh Mohammed, the alleged mastermind of the September 11, 2001 attacks, and three co-defendants. The ruling, issued on Wednesday, comes just weeks before the 25th anniversary of the attacks that killed nearly 3,000 people.

Air Force Lt. Col. Michael Schrama, the military commissions judge, rejected prosecutors' request for a January 2027 start, saying that would leave too little time for the "resolution of pretrial evidentiary and compliance motions." The judge's order outlines a detailed timeline: jury selection begins with a panel of service members, opening statements start 30 days after the panel is seated, and the defense presents its principal evidence 60 days after the prosecution concludes its case. The trial will end with a sentencing phase.

The case has been mired in legal battles for over two decades, with disputes over evidence, including confessions allegedly obtained under torture at CIA black sites, and the use of national security privilege. The trial date marks the latest milestone in what has been described as a prosecution beset by legal deadlock.

Mohammed, a U.S.-educated engineer born in Kuwait, was captured in Pakistan in 2003 and has been held at Guantanamo Bay since 2006. He is accused of conceiving the plot to crash hijacked planes into the World Trade Center and the Pentagon, and has claimed he planned the "9/11 operation from A-to-Z." His co-defendants are Walid bin Attash, accused of operating a training camp in Afghanistan; Ali Abdul Aziz Ali, allegedly involved in funding; and Mustafa al-Hawsawi, accused of supplying cash and other support.

The trial was previously scheduled in 2021 but cancelled. A plea deal that would have spared Mohammed and two co-defendants the death penalty in exchange for guilty pleas was thrown out by a federal appeals court last summer. The deal, which stipulated life sentences without parole and required the men to answer questions from victims' families, was revoked by then-Defense Secretary Lloyd Austin amid criticism from Republican lawmakers.

Legal challenges and delays

The path to trial has been complicated by pretrial disputes, including questions about the admissibility of evidence and the treatment of detainees. Defense lawyers have argued that the government's efforts to hide details of torture used at secret CIA prisons have contributed to the delay. The case has also faced challenges over the legitimacy of the military commission system itself.

Mohammed was charged and arraigned in 2008 with war crimes and murder. He remains one of the most well-known inmates at Guantanamo, a facility opened in 2002. About 15 prisoners are still detained there.

Families of victims react

Terry Strada, leader of 9/11 Families United and a widow of an attack victim, has long pushed for the men to face trial. The long-awaited trial date brings a measure of closure for families, though some have expressed frustration over the years of delays.
