I keep reading references to these sealed indictments .... have you any information on this @the_doc ?
The official Federal Court System website for this stuff is pacer.gov. It's a tally of sealed federal court orders by State, many of which orders (perhaps even most) are bound to be indictments. These have been formed over the past 12-15 months or so, apparently starting about 8 or 10 months into the Trump Presidency. Quite a few orders have remained sealed for an entire year.
The rate of formation of these sealed orders is reportedly 60 times higher than ever before in American history (way over 60,000 versus a normal rate less than 1000 per year). The dam is going to break soon, I think.
You can probably google the topic to get online commentary, breakdown by states, etc. Suffice it to say that the Trump administration is evidently planning an enormous sweep of some sort of network of crooks.
