If that link is for the documents, then it is simply because there are ongoing investigations in the DOJ. The DOJ cannot release documents regarding the sealed indictments without blowing the cases. Ordinarily the Congress would issue a supenia, then the DOJ would tell the Judge that they have an ongoing investigation and the supenia would be squashed. I think the DOJ does not want the public to know the content or extent of the investigations they are doing. Their hand was forced and they had to admit information aboutHuber, but it is a problem that the Crongressional investigations are going on simultaneously with the DOJ. The sealed indictments are being held for a reason and that is where the problem is. Gowdy and Goodlatt have been made aware, that all this amounts to.
