Khalid Sheikh Mohammed

A U.S. military court judge in Guantánamo Bay, Cuba, has set a trial date of Jan. 11, 2021, though a number of other deadlines would need to be met for the trial to begin then.

The attorney for one of the 9/11 defendants argues the Guantanamo military commission can't try his client, because the U.S. wasn't at war with al-Qaida at the time of the attacks.
