Why are they hiding the whistleblower's identity? Why is the whistle blower supposedly entitled to anonymity? My understanding is that the applicable  statutes provide that they cannot be targeted for retaliatory personnel actions (firing) because of any disclosures they make. Okay, fine, he can't be fired. That doesn’t meant they get to make allegations in secret and not face some scrutiny. Also, do you really want someone who maybe improperly (illegally) disclosed classified information to someone not authorized to receive it to retain their clearance? Or do you want to leave someone who possibly filed a false and/or malicious report in a position of responsibility?
