They've already started screaming "retaliation"... investigating the alleged criminal acts of the investigators is using the DOJ, FBI, CIA, et al. to retaliate against Trump's political enemies. The irony of that is, well, literally beyond words. These people are so delusional and/or liars of Biblical proportions, or something that can't be put into words! It literally takes my breath away when I see them make those kinds of statements. They do it knowing the 99+% of American citizens (and the voting non-citizens) don't know shit about the details of the whole deal, and don't really care all that much either way, either.
All the deep state alphabet agencies are doing everything they can to impede any investigation that will obviously disclose the corruption that has been ongoing by the top echelons of those agencies for decades. By the way, who advised the Bush administration that there were "weapons of mass destruction" in Iraq? Yeah, Clapper and Brennan... the very same. They've been full of shit liars for a long long time. Hopefully get taken down this time... way way way way down. I'm not especially hopeful anything of consequence will ever really happen to any of these people, but I do dream about it.
