Why is this even important. It’s NOT AGAINST THE LAW.
The only play the RATS have is to string out Mueller so that he can STOP investigations into the RAT criminal acts. Trump's investigations into the RAT Deep STATE must be stopped at all cost and making up law violations is all part of the game they are playing.
A small added benefit is that Mueller gets to harass and financially punish Trump supporters. The legal fees to fight Mueller's angry Democrats will easily financially ruin most people.
If a series of real investigations are begun from the DOJ, then many RATS are going to be arrested for very serious crimes. That of course includes Comey, Lynch, Susan Rice, Brewnnen/Clapper, MANY at the DOJ/FBI, in fact this string goes all the way to Hussein himself. WIth Rosenstien kicked to the curb, the RATS feel very threatened.
When Mueller's "investigation" is terminated, even he will not be surprised when they knock on his door to arrest him. His list of crimes is probably as long as the Clinton's.
