They are afraid to act for a lot of reasons.
Right now one of the big reasons is that the minute they dare take action against a democrat, communist, anarchist, etc. the media rips their throats out.
They are probably afraid of the deep state which has the ability to kill covertly or just ruin a person’s life. A lot of us felt obama had dirt on every politician thanks to all the illegal wire tapping by the NSA and that’s how he managed to leverage a lot of them. I’m sure the deep state keeps that info handy in case they need it too.

It is outright contempt that has become almost casual in its sense of utter impunity. This has nothing to do with the subject or the merits of the committee’s investigation.
The problem is that Congress has allowed the very agencies abusing these privileges in this instance, the FBI and Justice Department, to control whether their own officials can be prosecuted...
If the FBI was on a ship - this would be called a Mutiny
Mutiny is a criminal conspiracy among a group of people (typically members of the military or the crew of any ship, even if they are civilians) to openly oppose, change, or overthrow a lawful authority to which they are subject.
