Kiley's group cites as evidence a May 1973 U.S. News & World Report article by McCain in which he said he realized, on his third or fourth day of captivity after his plane was shot down in 1967, that his knee was so swollen the blood might pool in it and kill him. So he offered to give military information to his captors in exchange for medical treatment.
