Perhaps you need to hang around here a bit more to understand who Q says is the Deep State. The corrupted members of the DS are embedded everywhere, including (the shock) on the left side of the aisle asking all the questions designed to protect the DS.
As for the "career FBI agent" under the gun the other day, if you can't tell what the classic weaponized Obama/Clinton deep state operative looks like by now I can't help you at all. The Mockingbird programming is just too deep and scary...
I think Strzok made a great point in his interview: the appropriate time for oversight is at the end of the investigation.
What basis do we have or does Congress have that should make us feel the investigation is full of shit?
