There is the possibility the FBI campus cannot be cleansed...

It certainly can't be cleansed with a derp in charge. He's probably busy rebuilding the derp infrastructure.

I can't think of another federal investigative body, though. Could the military somehow serve that function?

I believe a lot of the CIA functions have been passed off to NSA, based on Q postings.

The ‘other’ fed inv.body would be clean agents moved off-campus to continue their work until the termites are gassed, then they move back home, or another site that can’t be comped. Quite common.
