So, how, where, or does Mulehead fit into all of this?
This very long article by Roger Stone on Daily Caller is probably the most complete information we have regarding your question to date:
The principles in the parent article for this thread are mentioned, to the extent that Mueller appears to have tried to cover up the charges announced today. Will these charges lead to more? Who knows. Maybe the charges are designed to put the squeeze to the American(s) who were profiting from the transfer. But since it appears that Mueller was trying to cover it all up, originally, the forces who wanted to cover it all up are likely still in power, at least to some degree.
