Former Texas state congressman Ben Barnes was in the news last week, admitting he was the one who got W into the Texas Air National Guard. He said he was "ashamed" at helping the sons of rich families stay out of Vietnam.
However, what he really ought to be ashamed about, and what he hasn't yet admitted, is later blackmailing W with the info. Read Greg Palast's story. Summary: by the time W was elected governor, Barnes had left public office and was a lobbyist; One of Barnes's clients was GTech Corp., who had the contract for the Texas state lottery; GTech was about to lose that contract due to allegations of corruption; Barnes had a talk with W; GTech got to keep the contract, worth $10 billion, and Barnes got a $23 million fee from GTech.
If Barnes gets around to admitting this is what happened, W goes to jail.
