O'Neill said no one could cross the border by river and he claimed in an audio tape that his publicist played to CNN that he, himself, had never been to Cambodia either. But in 1971, O'Neill said precisely the opposite to then President Richard Nixon.
O'NEILL: I was in Cambodia, sir. I worked along the border on the water.
NIXON: In a swift boat?
O'NEILL: Yes, sir.
