The Killian documents controversy involved six documents containing allegations about President George W. Bush's service in the Texas Air National Guard in 1972–73, allegedly typed in 1973. Dan Rather presented four of these documents as authentic in a 60 Minutes II broadcast aired by CBS on September 8, 2004, less than two months before the 2004 presidential election, but it was later found that CBS had failed to authenticate them. Several typewriter and typography experts soon concluded that they were forgeries. Lieutenant Colonel Bill Burkett provided the documents to CBS, but he claims to have burned the originals after faxing them copies.

Daniel Irvin Rather Jr. is an American journalist, commentator, and former national evening news anchor. He began his career in Texas, becoming a national name after his reporting saved thousands of lives during Hurricane Carla in September 1961. Rather spontaneously created the first radar weather report by overlaying a transparent map over a radar image of Hurricane Carla. In his first national broadcast, he helped initiate the successful evacuation of 350,000 people. He reported on some of the most significant events of the modern age, such as the fall of the Berlin Wall, the Gulf War, 9/11, the Iraq War, and the war on terror.
