It would have been much cheaper for Hastert to tell the truth
If Hastert had gone to the FBI when the extortion effort began he would have been better off and the person demanding the hush money would have been the like recipient of an indictment. So why didn't his alleged victim just bring a case against him? I suspect because he thought he could get more doing it the way he did. It will be interesting to see if any charges are filed against the recipient of the hush money.
