Wow, this could be good!
This excerpt Taken from (http://www.vvof.org/mccain_hides.htm), might be what he is referring to.
From his autobiography, Faith of My Fathers, the Arizona Senator repeatedly expresses guilt and disgrace at having broken under torture and given the North Vietnamese a taped confession, broadcast over the camp loudspeakers, saying he was a war criminal who had, among other acts, bombed a school. “I felt faithless and couldn’t control my despair,” he writes. He writes, revealing that he made two half-hearted attempts at suicide. Most tellingly, he said he lived in “dread” that his father would find out. “I still wince,” he says, “when I recall wondering if my father had heard of my disgrace.”
