Notables: Anon Specualtes that Reluctant Witness in FISA Investigation is State Department Exec Kathleen Kavalec Who Covered Russia. https://www.foxnews.com/politics/reluctant-witnesses-in-fisa-abuse-probe-agree-to-talk-to-doj-inspector-general Anon's specualtion: While the “reluctant witness” is not specifically identified by Herridge in her reporting, as you can see above there is enough background material to identify it is likely former State Department official Kathleen Kavalec. Kathleen Kavalec was the Deputy Assistant Secretary – Department of State, Bureau of European and Eurasian Affairs, serving under Victoria Nuland and covered Russia as part of her State Dept. duties.  Kavalec was contacted by Christopher Steele prior to the FISA application on Carter Page being sought by the FBI and DOJ.  Kavalec wrote a series of notes and emails to the FBI undercutting the dossier central claims made by Steele. My Guess That FISA application reference to October 2016 US State Department source IS the Kavalec email. If so…..this may be THE indisputable LIE. 1) The FBI didn’t reveal the actual source: Steele (This would be at least the 3rd time in the application they are using Steele in circular substantiation) 2) They hid Kavalac’s doubts, warnings and validations.
