Final answer:
The claim is false; individuals with SCI access must report adverse information about others with SCI access, as it affects national security.
Step-by-step explanation:
The statement in question is false. Individuals who hold a Security Clearance Information (SCI) access are required to report any adverse information they become aware of that could impact someone else's eligibility for SCI access. This means if you are aware of someone else who also has SCI access and they have potentially disqualifying behavior, it is your responsibility to report this information. Failing to report such information can have serious implications for national security and the safety of classified information.
