I think that's a very understandable response seeing as they colluded with Russia, serve their aims, and have every reason to worry that their continued efforts to serve Russia and undermine America will cause American government employees to be upset with them. It would be mighty silly of them NOT to take precautions against their efforts being undermined. Of course this effort of theirs will face attempts to undermine it: it's entirely hostile effort on every level, obviously in service of a hostile foreign power. Why would they trust they won't be resisted? Not everybody is foolish.
