Oh, BS. Bush was a congressman from Houston in 1967 when I moved there. His time with the CIA began in the 70s.
Then WHO is that in the pictures? I personally don't know, but the subject certainly is a "dead ringer" for Bush Sr. and I can see why many think he was involved, particularly since he so vehemently disputes even being present there. Shakespeare said it best" "methinks he doth protest too much". Bush's "official" biography may have him working with the CIA in the 70's, but many reports say he was working with them as early as '61.
