Well that settles it. No need for any oversight committees, and no need for the FBI or DOJ to ever send anyone to testify in congress.
I hope the staffer is just making up BS and doesn't really believe what they said. If they honestly believe what they told you they are really ignorant.
I can assure the staffer was idealistic, sincere and uninformed.
If I complained to the FBI I would expect to get a visit from two agents and a tax audit.
