“CBS News has confirmed military prosecutors and defense attorneys are negotiating potential plea deals that could take the death penalty off the table for five defendants charged in connection with the 9/11 attack – and some families of victims are upset by the news, reports CBS News senior investigative correspondent Catherine Herridge. The five defendants (including Khalid Shaikh Mohammed, the self-described architect of 9/11) are all held at the military prison in Guantanamo Bay, Cuba, and were formally charged in 2008 with helping to plan the attack. But their cases have stalled over access to CIA evidence and, recently, over COVID delays. Sunday marked 21 years since the terror plot that killed nearly 3,000 people on U.S. soil. Among the victims was pilot Charles Burlingame. On 9/11, al Qaeda terrorists took over Burlingame's American Airlines Flight 77, slamming it into the Pentagon. “He was living his dream,” Burlingame's sister, Debra, told Herridge. Burlingame was more than a war hero to his family, who affectionately called him Chic. “He was really our touchstone,” said Debra. “He still is.” Before this year's anniversary, Debra shared his story at New York's 9/11 Memorial.”
