Adultery is not a federal crime. Anyway, it says that he wasn't the target of the criminal investigation. Presumably, Broadwell was.
I know it’s not a crime, I was just explaining that military rules would not apply to him because he wasn’t a member of the military, just an employee of the Federal Government.
Personally I think the Kelly harassment by Broadwell angle is just a story cooked up by the FBI / Holder by the Obama administration to “explain” how the investigation came about. It also provides for a timeline which makes it ppear more believable. I don’t buy it for a second; it sounds contrived. In fact, I bet scrutiny of Kelly’s background will reveal even more reasons to disbelieve it.
