In the James case, Kristin Bird and Elizabeth Yusi (prosecutors in EDVA) were both fired for refusing to bring charges, only to be replaced by Trump's personal attorney Lindsey Halligan (who is not even a prosecutor).
In the Comey case, again they fired Erik Siebert, also from EDVA, because he wouldn't prosecute. They put Trump's personal attorney on instead and she immediately gave the prosecution a greenlight against a tight statute of limitations deadline.
Just watch: today there was a report that prosecutors in Maryland are hesitant to bring charges against Adam Schiff. My guess is whoever is gumming up the works there will be fired and replaced by another Halligan.
