The NSA is managed by the NSA director, an independently appointed and confirmed office separate from the Office of the Director of National Intelligence. The DNI does have the authority to restrict funds to the NSA, and sets certain priorities, policy, etc. but the NSA director is not beholden to the DNI and makes their hiring and firing decisions independently. They’re also, currently and historically though not required by statute, a flag officer in the US military and dual-hatted as the commander of CYBERCOM. All this is to say, chaos in the office of the DNI does not necessarily impact the NSA.
