It doesn’t really matter how ‘livid’ they are. The agents themselves have limited power and influence. They would have to leave their jobs and separate from the FBI in order to truly open up. Perhaps not even then, would they be allowed full disclosure without violated some signed oath.
Those who should be angry, such as Reince Preibus, Paul Ryan and Mitch McConnell are ‘too busy’.
The sad fact is, for the American people to get the truth, these agents would have to claim political asylum in Russia - only then could they safely tell what they know.
Too busy working to get Hillary elected.
