Reporter: How hard is it to walk out of a SCIF with classified material?
Kirby: Everybody who goes into a SCIF knows what the requirements are; to go in, and knows what the requirements are to go out…you certainly can't leave with material unless that material is appropriately secured.
Reporter: Usually what happens to someone in the chain in command if they do leave with a piece of classified material that they're not supposed to have, or that is not secured?
Kirby: If you do it inadvertently…you self-report. Which is exactly what [Biden] did. Self-reported. And you make sure that you get the material back, secured where it belongs, and that you are transparent about it.
