“I suspect they are concerned longtime, reliable informants will be exposed.”
Then they should start by cleaning their own house, and fire the “agent” who told Chris Steele in Rome that the FBI had a source in the Trump campaign !
Where is the outrage from these “FBI supporters” about that little gem ?
You do now that information about the agent and Steele has been exposed as fake news?
There is a mess to clean up in the FBI, but the house cleaning needed is on the 7th Floor of the FBI which is headquarters. They have been infiltrated by an Obama (Comey) commissar who was never an agent but an appointee. Who then developed his team of troublemakers from several other appointees and a couple of rogue agents. I understand from Fox, they are all under investigation now.
