 In May 2000 , challenged by a skeptical U.S. News & World Report magazine article , the AP team did additional archival research , and reported that one of nine ex @-@ soldiers quoted in the original No Gun Ri article , Edward L. Daily , had incorrectly identified himself as an eyewitness , and instead had been passing on second @-@ hand information . A Pentagon spokesman said that this would not affect the Army 's No Gun Ri investigation , noting Daily was " just one guy of many we 've been talking to " . Army officer Robert Bateman , a 7th Cavalry veteran , who collaborated on the U.S. News & World Report article with a fellow 7th Cavalry association member , also published a book , No Gun Ri : A Military History of the Korean War Incident , repeating his contentions that the AP reporting was flawed . The AP 's methods and conclusions were defended by the AP in a lengthy , detailed refutation and by others . The Pulitzer committee reaffirmed its award and the credibility of the AP reporting .
