Right now I doubt much will be done to the miscreant FBI people who showed they should not have been anywhere near "investigations" of HilLIARy or Trump, plus or minus Strzok. Not unless someone ass-kicks the Justice Department into doing it, using steel-toed boots. I think it toasts the FBI with Congress wrt the FBI "investigations" of HilLIARy and Trump, and should also toast Mueller's travesty with Congress (though that would take a bit of courage, for which R Congress Critters are not renowned).
What should happen is every FBI agent who texted Hate-Trump crap while having anything to do with the "investigations" of HilLIARy and Trump, and every FBI agent who leaked to the MSM (bribed and unbribed) should be summarily canned for cause, and if any laws were broken, prosecuted. Up to and including the head of the FBI, if applicable. The damage dome to the FBI's credibility will not be limited to HilLIARy. Trump, and the 2016 election.
