You are not understanding my comment. I am not suggesting that your actions are illegal. You would be drawing the attention of the DOJ to potentially illegal actions. That is perfectly acceptable and is not a problem whether those actions are illegal or not.
I am suggesting a way to bolster your charge of "extortion" against the Senators. While their threats of Federal agency action are despicable, they are not illegal. However, if they suggested prosecution, then that could be viewed as either "prior restraint" or threatening prosecution, which is illegal.
Ah, I understand now. Thanks for the clarification!
