Secret warrants... Permanently secret ("sealed") warrants... anyone who reveals the existence of a secret warrant subject to fine and prison...
h/t SayUncle, who observes that
The public’s business should be done in public.There are legitimate reasons for secrecy, but each should be handled on a case-by-case basis, not covered by a blanket that allows the Powers That Be to cover up their mistakes and vendettas.

This is why we shouldn’t assume that someone is a friend of freedom, just because he signed a couple of pro-2A bills (one of which had been passed for the third time).
