My thoughts too. It's not something you would boldly declare if there were a whole team of FBI agents working on a case against you. My thoughts are Lynch has told her nothing will come of the charges and that the investigation is a smokescreen to convince the public that something is being done about it.
“The way she confidently plays down the investigation and firmly states she won’t get indicted is just proof to me she’s already been told she’s in the clear.”
I thinks it’s just bravado.
