He returned to Utah to prevent the sale of a United States Senatorship by the Mormon Church; and, though he was himself defeated for re-election, he helped to hold the Utah legislature in a deadlock that prevented the selection of a successor to his seat. He fought to compel the leaders of the Church to fulfill the pledges which they had authorized him to give in Washington when statehood was being obtained. After his father's death, when these pledges began to be openly violated, he directed his attack particularly against Joseph F. Smith, the new President of the Church, who was principally responsible for the Church's breach of public faith. Through the columns of the Salt Lake Tribune he exposed the treasonable return to the practice of polygamy which Joseph F. Smith had secretly authorized and encouraged. He opposed the election of Apostle Reed Smoot to the United States Senate, as a violation of the statehood pledges. He criticized the financial absolutism of the Mormon Prophet, which Smith was establishing in partnership with "the Plunderbund." He was finally excommunicated and ostracized, by his father's successors in power, for championing the political and social liberties of the Mormon people whom he had helped to save from destruction and whose statehood sovereignty he had so largely obtained. When the partnership of the Church and "the Interests" prevented the expulsion of Apostle Smoot from the Senate, Senator Cannon withdrew from Utah, convinced that nothing could be done for the Mormons so long as the national administration sustained the sovereignty of the Mormon kingdom as a co-ordinate power in this Republic. For the last few years he has been a newspaper editor in Denver, Colorado--on the Denver Times and the Rocky Mountain News--helping the reform movement in Colorado against the corporation control of that state, and waiting for the opportunity to renew his long fight for the Mormon people. In the following narrative he returns to that fight. In fulfillment of a promise made before he left Utah--and seeing now, in the new "insurgency," the hope of freeing Utah from slavery to "the System"--he here addresses himself to the task of exposing the treasons and tyrannies of the Mormon Prophet and the consequent miseries among his people.
