John Kennedy actually said...
In the event that a head of an agency deems space assigned or reassigned to his agency to be unsuitable, and the agency head and the Administrator are unable to resolve the matter, the former, as promptly as may be practicable and in no event later than the effective date of the Administrator's assignment or reassignment, may make a written report thereof, including information and views pertinent thereto, to the President or to the Director of the Bureau of the Budget.
