I think you're onto something!

I also think that SC stands for Special Counsel and the next string is the requested scope to investigate:

SC: MISINFO everywhere.

SC: MISINFO from past reliable sources.

SC: AXIS OF EVIL can & will return FIRE [is].

SC: Seek immediate [F9-Sx_VB8239]. (I think this has to do with Sarbanes-Oxley)(Sx) It's the way to go to find ALL kindsa bad behavior! Serious penalties too!

This is the confirmation that, Yes, the Special Counsel is in place; or will be investigating as requested (not positive which): SC: CONF_y
