The Justice for 9/11 Act aims to ensure trials for individuals detained at Guantanamo Bay—specifically, Khalid Shaikh Mohammad, Walid Muhammad Salih Mubarak Bin Attash, and Mustafa Ahmed Adam al Hawsawi—in relation to the September 11, 2001, terrorist attack. It clarifies that plea agreements or judgments do not prevent trials under existing laws and allows for the consideration of a death sentence. If convicted, these individuals must be held in solitary confinement at Guantanamo Bay, with strict limitations on communication and transfer.
