You have proof there isn’t an investigation of that which you speak of???
Investigations to be fully complete take time (and covert action)...
First there is plenty of evidence to indict Hillary for obstruction of justice NOW. But as to your question, a real investigation would involve empaneling a grand jury, calling witnesses and issuing subpoenas, none of which has been done. You just keep on believing though. I know, maybe their just waiting for the second term so they don’t have to worry about reelection! That’s the ticket!
