KHOU-TV's investigative team, "The 11 News Defenders", began an investigation into the failure of Firestone Wilderness AT tires on several vehicles (including the Ford Explorer). These reports garnered the station and the team of Anna Werner, investigative producer David Raziq, and investigative photojournalist/editor Chris Henao several national awards, including the Edward R. Murrow, George Foster Peabody, and Columbia University DuPont Award. Among the journalists who have worked for KHOU, the best known are former CBS Evening News anchor Dan Rather, Linda Ellerbee, and Jessica Savitch.
