Surely as CIC, he can and better bust this Rear Admiral. Sounds like gross insubordination to me. Reduction in rank and kick him out.
Never having been in the military I couldn't answer that.
As POTUS and CIC, President Trump has unfettered power under Article II, Section 2 of the Constitution to require resignation of a flag officer...See Truman/McArthur dust up for reference...
The Rear Admiral should be on the street most rikki-tik...
So do we go to Seaman Green (former Rear Admiral Collin Green)?
Let him fight the USA CIC with all the lawyers he can find. He’ll lose. ;-)
A transfer to the new SEAL base at Ice Station Zebra would also work.
Give him his very own command of one.
