You can't sue a prosecutor for doing their job...

Prosecutor Immunity
One of the biggest challenges in malicious prosecution cases based on the filing of criminal charges is prosecutor immunity. State and federal laws give prosecutors and other law enforcement employees immunity from liability for malicious prosecution. This immunity is meant to protect prosecutors and law enforcement so they can do their job without constantly having to defend against accusations of malicious prosecution. The concern is that every person who claims innocence might try to sue the prosecutor for wrongful prosecution.
There are, however, limits to this immunity. If the person bringing a malicious prosecution suit can show that the prosecutor acted outside his authority in the process of instigating or pursuing a criminal case, the immunity will not extend to those actions in most jurisdictions. If the businessman can prove, for example, that the prosecutor paid a witness to testify to certain things or created false documents, the prosecutor probably would not have immunity, because those actions would be outside the scope of the prosecutor’s job."
Suing for Damages: Malicious Prosecution in a Criminal Case
You didnt read everything you posted and the what he is suing for, did ya?
Yes I have, and Mueller didn't do ANY of the things that would cause him not to be protected under the immunity.
well, thats what the suit is about, your honor.
The Manafort lawsuit alleges Deputy Attorney General Rod Rosenstein and Mueller have unlawfully exceeded the authorities allowed under the law governing special counsel appointments. The lawsuit contends that the order Rosenstein signed to appoint Mueller "exceeds the scope of Mr. Rosenstein's authority to appoint special counsel as well as specific restrictions on the scope of such appointments."
The focus is on a part of the Rosenstein order that says that Mueller may investigate "any matters that arose or may arise directly from the investigation." The Manafort lawyers say that goes beyond what the law allows Rosenstein to empower Mueller to do.
The Rosenstein order gives Mueller "carte blanche to investigate and pursue criminal charges in connection with anything he stumbles across while investigating, no matter how remote from the specific matter identified as the subject of the appointment order," the lawsuit says.
And it will be thrown out of court, and rather quickly. Mueller did his job. I hate to break this to you, but a person can be charged with a separate crime if it is discovered while conducting an investigation into a different one. It's all about probable cause.
