I may be overly cynical. My view of Sessions is that he wouldn’t be allowing people to ask questions re Uranium One if there was any danger of people being charged, tried, convicted and going to prison. Look at all the recent, established, unquestionable crimes Hillary has committed. No active investigation. But Jeff has to do something, so he picks a crime that was committed over 7 yrs ago. It just fits the pattern too well.
I hope I am not being overly optimistic. I think when an investigation is ongoing, any crime found can be prosecuted, and there are probably a multitude of them still under any statute of limitations, including the email servers and other crimes. So I think any investigation is a good sign, and I suspect, as it should be, that there is much more going on than we can currently see.
