Why did the FBI withhold the FD-1023 from Congress?
The the FD-1023 is the form special agents use to record raw, unverified reporting from confidential human sources (CHSs). FD-1023s merely document that information; they do not reflect the conclusions of investigators based on a fuller context or understanding. Recording this information does not validate it, establish its credibility, or weigh it against other information known or developed by the FBI in our investigations.
Protecting this type of information from wider disclosure is crucial to our ability to recruit sources and ensure the safety of the source or others mentioned in the reporting. CHSs are critical to cases across all FBI programs -- whether it's violent crime, drug cartels, or terrorism. It would be difficult to effectively recruit these sources if we can't assure them of their confidentiality. See socxfbi.org link
