I don't know what you're thinking, but it sounds to me like Murtha is trying to inoculate himself from an ethics investigation. After his little tirade yesterday, now he can say he's being persecuted if pubbies charge him....and MediaCrats (especially David Schuster/Chris Matthews) will compare it to the White House "smear" on the sainted Joe Wilson!
Yep, that's precisely what I was thinking.
