Woodrow Wilson actually said...
Hereafter when a vacancy occurs in the position of postmaster of any office of the first, second, or third class as the result of death, resignation, removal, or, on the recommendation of the First Assistant Postmaster General, approved by the Postmaster General, to the effect that the efficiency or needs of the service requires that a change shall be made, the Postmaster General shall certify the fact to the Civil Service Commission which shall forthwith hold an open competitive examination to test the fitness of applicants to fill such vacancy.
