They already know Simpson was feeding ohr. And know about nellie, etc...
Hmm...
If we can see the outlines the investigators have had the details for a very long time. It pays to remember that we first learned about Strzok and Page less than a year ago, in early December 2017. All that we know of the conspirators we have learned since then.
But the IG investigation, Horowitz, started a few days before Trump took office. And Admiral Rogers of NSA visited Trump Tower about 2 weeks after the election. Meaning that team Trump has had a good idea of the conspiracy since before day one. And I suspect that they began planning on how to expose and destroy it beginning right then.
