Abolish or split up the DC Circuit court. Form a different circuit court because DC is not a state and therefore doesn’t need a circuit court.
Congress establishes judicial circuits. Congress would have to disestablish it or split it up.
Constitution, Art 3: The Trial of all Crimes, except in Cases of Impeachment; shall be by Jury; and such Trial shall be held in the State where the said Crimes shall have been committed; but when not committed within any State, the Trial shall be at such Place or Places as the Congress may by Law have directed.
DC is not a state. Congress can and should remove jurisdiction for serious crimes by or against public officials away from the DC leftist/ghetto/swamp courts. And take investigation responsibility away from the FBI headquarters clique. Even randomly assigning such cases to US district courts would be better than this.
Good luck getting it through the Senate unless we do what the Ds have promised to do and eliminate the modern filibuster.
