With the election of William D. Coleman as president in 1896, Gibson was appointed Secretary of the Interior. He was Secretary of State, when Coleman resigned in 1900, and since there was no vice-president, Gibson was chosen to succeed him. He won the election that same year, and served until 1904, when he was succeeded by his Secretary of the Treasury, Arthur Barclay.
Marshall, however, was considered to be incompetent and the Legislature repealed the existing presidential succession law (dating from 1873) and chose Secretary of State GarretsonW. Gibson as the new President.
Secondly, Coleman failed to properly communicate with members of his Cabinet, among whom Secretaries GarretsonGibson and Arthur Barclay (Finance), who thus did not know his intentions and plans for the development of the interior and its population and hence had difficulties in explaining and defending these to political adversaries.
Thirdly, President Coleman distanced himself of the prevailing policy among his fellow TWP partisans that preferred the use of peaceful means to solve inter-tribal disputes.
