Speaking on ABC 's '' Good Morning America '' on March 18 , 2003 , he promised that " i f the Americans go in and overthrow Saddam Hussein and it 's clean of weapons of mass destruction ... I will apologize to the nation , and I will not trust the Bush administration again . " In another appearance on the same program on February 10 , 2004 , he responded to repeated requests for him to honor his pledge : " My analysis was wrong and I 'm sorry . I was wrong . I 'm not pleased about it at all . " With regard to his trust in the government , he said , " I am much more skeptical of the Bush administration now than I was at that time . " Beginning in 2005 , he periodically denounced George Tiller , a Kansas-based physician who specialized in second - and third-trimester abortions , often referring to him as " Tiller the baby killer .

O'Reilly responded to the criticism by saying " no backpedaling here ... every single thing we said about Tiller was true . " In early 2007 , researchers from the Indiana University School of Journalism published a report that analyzed his " Talking Points Memo " segment . Using analysis techniques developed in the 1930s by the Institute for Propaganda Analysis , the study concluded that he used propaganda , frequently engaged in name calling , and consistently cast non-Americans as threats and never " in the role of victim or hero . " He responded , asserting that " the terms ' conservative ' , ' liberal ' , ' left ' , ' right ' , ' progressive ' , ' traditional ' and ' centrist ' were considered name-calling if they were associated with a problem or social ill . " The study 's authors said that those terms were only considered name-calling when linked to derogatory qualifiers . Fox News producer Ron Mitchell wrote an op-ed in which he accused the study 's authors of seeking to manipulate their research to fit a predetermined outcome . Mitchell argued that by using tools developed for examining propaganda , the researchers presupposed that he propagandized
