From here, it looks as if the aide made that comment. However, I specifically know of an admiral that was 'fired' for "Poor Command Climate"; I suspect that this Kearney is another ringer like Sestak and agree he needs to be removed from any position of leadership.
This part alone is troubling:
“In March, Gen. Kearney finalized a decision to redeploy all 120 members of the Marine Special Operations Command Fox Company out of Afghanistan, halfway through an internal preliminary investigation into the Marines’ response to an ambush on March 4.”
