The Guardian charted the path the dirty dossier made from a British intelligence professional to Sen. John McCain and then the FBI
McCain, 80, put out a statement Wednesday saying that he was the bureau's source of the controversial dossier
The Arizona Republican found out about the dossier's existence while at a meeting in Canada and dispatched an emissary to hunt it down
He met an ex-British diplomat in Canada - now identified as Sir Andrew Wood -who in one version of events told him about the file
Wood is a former associate of Tony Blair the ex-British prime minister, and admitted talking to McCain
He issued a nuanced statement saying he did not give McCain the dossier and had 'done nothing wrong' - but he did not deny telling McCain the file existed
