Yes. It is most assuredly true. Barnes became Lieutenant Governor in 1969 but Bush joined up in 1968.
All the news stories quote Barnes' allegation with an ellipses about halfway through the quote where they took something out. If you look at the video the ellipses part says "when I was Lieutenant Governor." The media cut that part out of the newspapers because they KNEW that Barnes wasn't Lieutenant Governor when Bush joined up.
So then it looks like W is ropadoping again. I can hardly wait for CBS to get egg all over its face for the upcoming 60 Minutes piece.
