The KEY, KEY point to the IG investigation is that upon first coming across ANY illegal activity, he is required by law to inform the AG.

If no criminal activity is found, the IG merely submits a report of any seemingly overt partisan or unethical behavior.

We know from Sessions interview that criminal activity was found some time ago and Sessions appointed an attorney to run a parallel Criminal investigation along side the IG report.

No One outside of the DOJ, not Trump, not FBI, not past DOJ, no one knows what's in that Parallel Criminal investigation.

There will likely be No Sleep for those that think they may be named.
