Acting Mayor Ardolph Kline's elected successor, John Purroy Mitchel, indicated before taking office at noon on January 1, 1914, that he would not keep Commissioner Waldo in office. Waldo tendered his resignation effective at midnight December 31, 1913, after transferring or accepting resignations from most of the department's senior officers and specialists. Amid much confusion and discord, Mayor Kline (who had taken office after Mayor Gaynor's death in September 1913) refused to accept Waldo's resignation (which would have left the Department without leaders for the first 12 hours after New Year's Eve) and fired him instead.
