Not sure how this is supposed to work... Federal prosecutors pretty much have air-tight bulletproof level imunity.
The government can waive Sovereign Immunity in certain circumstances - i.e. the government agrees to be sued.
In Mueller’s case not clear, but the stretch to get him on a claim is a lot shorter then trying to claim that a personal payment to a female shakedown artist is a campaign contribution.

Here, and or how they can lose it: Hint think Randy Weaver /Ruby Ridge/Standoff in Idaho in 1992 & Prosecutorial Immunity LOST / Denied held by 9th Circuit.
Excerpts below from the above titled case.
We have grown accustomed to relying on the federal government to protect our liberties against the excesses of state law enforcement. Federal prosecutors may bring criminal charges against state police who violate the rights of citizens. See, e.g., Koon v. United States, 518 U.S. 81, 116 S.Ct. 2035, 135 L.Ed.2d 392 (1996). Those citizens may also seek redress by bringing private suits in federal court. See 42 U.S.C. § 1983. While state prosecutions of federal officers are less common, they provide an avenue of redress on the flip side of the federalism coin. When federal officers violate the Constitution, either through malice or excessive zeal, they can be held accountable for violating the state's criminal laws.
If federal agents are to perform their duties vigorously, however, they cannot be unduly constrained by fear of state prosecutions. Accordingly, the Supreme Court has held that the Supremacy Clause cloaks federal agents with immunity if they act reasonably in carrying out their responsibilities. See In re Neagle, 135 U.S. 1, 75, 10 S.Ct. 658, 34 L.Ed. 55 (1890). We explore the outer bounds of Supremacy Clause immunity in the context of Idaho's attempt to prosecute FBI Special Agent Lon T. Horiuchi for killing Vicki Weaver during the infamous Ruby Ridge incident.
Cliff notes version of the "State of IDAHO, Plaintiff-Appellant, v. Lon T. HORIUCHI," is simply that a Complaining WITNESS (Read Complaining witness: as a Cop {city or county}/Federal Agent / "State Actor" or Prosecutor[s] state or Federal) when they "LIE" under oath in the charging {Complaining} documents, they lose their Prosecutorial Immunity or {Cop {city or county}/Federal Agent / "State Actor"} Qualifying / Qualified Immunity.
