That's exactly the legal question I had in mind: how long can this affidavit remain sealed?
Aren't there rules or certain "rights" --regarding time limits, etc., whereby it can be in time unsealed?
In the meantime...I found the article concerning Jefferson. Don't know anything about this website's bias, but here is a quote from the article and link at bottom:
"But although Justice Department prosecutors have reportedly been poised to indict Jefferson for months, the case remains tangled in the legal fray caused by the FBI's raid of Jefferson's congressional office. And it won't be until April at the earliest before an appeals court begins to consider the fate of a select few of the seized documents -- which Jefferson's lawyer argues are protected as legislative materials under the Constitution's Speech or Debate clause. That means it may well be summer before prosecutors actually bring an indictment."
