There is quite a controversy brewing over a POW story McCain told during the Saddleback forum. Many are questioning whether John McCain stole this old story directly from the Russian author, Solzhenitsyn, an author with whom he was quite familiar before McCain's own controversial cross in the dirt story was ever revealed to the press.
To date, this personal story has only been backed up by one high ranking Republican figure who vaguely remembers it.
Andrew Sullivan has been running what is most likely the best research regarding John McCain's alleged interaction with a Vietnamese guard who supposedly drew a simple cross in the dirt to show his own Christianity. This POW Christmas story has been repeated over the years by Mr. McCain in a most touching way, but with a most confusing time line.
I would like to add that John McCain is not above borrowing from other sources as evidenced by his theft through copyright infringement of Jackson Browne and John Mellencamp songs. John McCain was also not above stealing his recent foreign policy speeches directly from the pages of Wikipedia as well.
