Man, it is tough to keep up with the news from D.C. as a result of the recent document declassification. Apparently, there are more documents coming soon.
Remember, Crossfire Razor was being closed on 1/4/17. The FBI was running a counter-intel op against Flynn - he was the target. The FBI was going to close that on 1/4/17 until Strzok texted the case agent and said to keep it open based on orders from the 7th Floor (Comey / McCabe). Did someone tell a fib when testifying to Congress? We shall see.
In the embedded video in the link, listen to Comey testifying about how the FBI is obsessive when it comes to the FISA process. We now know that he was completely full of shit when he gave that testimony. Maybe he deserves an Oscar for sincerity. The IG's random sampling of their FISA compliance showed anything but an obsessive culture.
