Poor judgement from one of the few guys in the Navy that have a carrier. Or any ship, for that matter.
The 'help' he was asking for was to be able to evacuate the lion's share of his crew ashore in Guam, leaving a front line military asset unusable for an indefinite period. I would expect any capt. or commander of any part of the strategic triad would get the same answer. If they suddenly needed to deploy to counter Iranian aggression, would we have to wait weeks for them to get underway?
At least as a Navy Captain (O-6), he likely is in a position where he can retire comfortably after he ran his career aground.
