I ripped out cable 10 years ago after Clinton was acquitted in the Senate, so I don’t have first hand knowledge. I read that he has appeared on TV and had some involvement in comment on the Plame affair.
Seems to me that I either read or heard on the radio that Johnson was on Fox for comment at the beginning of the Plame affair and he said something that caused him to be dropped like a hot potato. Until you said something about military intelligence, CIA, I couldn't place him.
