The U.S. Defense Department is set to appeal a military judge's recent ruling that allows three defendants in the September 11, 2001 attacks, including alleged mastermind Khalid Sheikh Mohammed, to enter guilty pleas in exchange for avoiding the death penalty. This decision follows the judge's approval of plea agreements that would spare the defendants from capital punishment. The appeal aims to challenge the validity of these agreements, which have sparked significant public and political discourse, with some figures calling for continued efforts to ensure justice for the victims of the attacks. The legal proceedings are expected to unfold as families of the victims prepare to confront the defendants in court.
