Sorry, but yet another suitability question, this one regarding a secret clearance (granted by DISCO) being upgraded by adding an SCI component from another agency.
How important are still-secret-from-the-spouse extramarital affairs in this process, if those affairs were conducted while the subject had the S clearance? For example, multiple affairs that lasted a few years each, over the course of a decade or so, ceasing a year or two in the past? The spouse is somewhat aware that recent illicit email communications occurred, but is not aware of the full extent of the affairs.
I understand that this might fall under the personal conduct criterion, and might demonstrate to the investigators a pattern of dishonesty. Is this likely to come out in the clearance investigation? Is it the type of thing that should be self-reported?
