Yes, ADVISOR - Obama made the final decisions - an 'input' doesn't mean shit, the CIC makes the decisions.
exGOPer admits that a President has no requirement to follow recommendations of his Cabinet secretaries and can issue final decisions without need of their inputs.
So according to exGOPer's correct interpretation of the Constitution, Trump had the authority to fire Comey, and Trump also has the Constitutional authority to end the Mueller probe at any time of his choosing. Nicely done exGOPer, I guess the broken clock saying, is correct.
