Sounds like a Catch-22. Can’t release due to ongoing investigation. Can’t complete the investigation because ???
Horowitz’ investigation is finished. Read that today. Horowitz can only investigate, from what I’ve read, persons currently working for the DoJ/FBI. That is one reason apparently or the reason, why Ohr and others were kept on at the DoJ/FBI for some time, as they were being actively investigated. They were demoted and doing some sort of make work jobs no doubt.
Once investigations by Huber and Durham (and whoever else is assisting or working under them) are finished, then the Fun begins!
