In this [interview](https://www.msnbc.com/rachel-maddow/watch/evidence-of-mueller-counterintel-interests-seen-in-cohen-warrants-60152901742) with Rachel Maddow, Congressman Jim Himes made some interesting assertions about the counterintelligence investigation into Trump, starting at around 4:00.
He stated that often the intelligence community won’t charge a counterintelligence target, because greater value for national security can be obtained from simply continuing to investigate.
This raises the question for me, did the counterintelligence investigation that Mueller was overseeing end, or was it simply handed off? The Mueller report contains virtually nothing on the counterintelligence investigation, and in fact seems to purposely conceal information around Flynn and several other topics.
If it is still ongoing, that would explain why Mueller provided so few answers to the fundamental counterintelligence questions in the investigation. Instead he focused on the easily provable obstruction, and stayed silent on so many vital points.
