Why haven’t cheating FBI lovebirds been fired yet?

I find it amazing that Peter Strzok and Lisa Page, those Trump-hating, spouse-cheating FBI lovebirds, haven’t been fired yet — even though they greatly compromised the probe into Hillary Clinton’s mishandling of her government emails. What’s even more astounding is that a source tells me that neither has lost security clearance despite being demoted. I’m told that clearances are routinely pulled even when someone is caught having an extramarital affair.
