“The Attorney General is appointed by and serves at the will of the President. Period. By extension, the Special Counsel who was appointed by the AG’s office is subject to termination without cause by the AG or acting AG. No judicial review of any dismissal is justified nor is it required.”
All true, but doesn’t address the issue. The fact that a system is built to function a certain way does not mean it should be maintained that way in the face of clear evidence that it doesn’t function well. So what is or isn’t required now is begging the question. All systems can be improved, and one way of improving this one is to ensure that an investigation into possible wrong-doing is continued to its conclusion, unless there has been bad-faith action on the part of the investigator. Which would be determined in a judicial review, not arbitrarily by an individual who may have a lot to lose if the investigation continues.
