October 1911, Taft's Justice Department brought suit against U.S. Steel, demanding that over a hundred of its subsidiaries be granted corporate independence, and naming as defendants many prominent business executives and financiers. The pleadings in the case had not been reviewed by Taft, and alleged that Roosevelt "had fostered monopoly, and had been duped by clever industrialists". Roosevelt was offended by the references to him and his administration in the pleadings, and felt that Taft could not evade command responsibility by saying he did not know of them. Taft sent a special message to Congress on the need for a revamped antitrust statute when it convened its regular session in December 1911, but it took no action. Another antitrust case that had political repercussions for Taft was that brought against the International Harvester Company, the large manufacturer of farm equipment, in early 1912. As Roosevelt's administration had investigated International Harvester, but had taken no action (a decision Taft had supported), the suit became caught up in Roosevelt's challenge for the Republican presidential nomination. Supporters of Taft alleged that Roosevelt had acted improperly; the former president blasted Taft for waiting three and a half years, and until he was under challenge, to reverse a decision he had supported. Ballinger–Pinchot affair Roosevelt was an ardent conservationist, assisted in this by like-minded appointees, including Interior Secretary James R. Garfield and Chief Forester Gifford Pinchot. Taft agreed with the need for conservation, but felt it should be accomplished by legislation rather than executive order. He did not retain Garfield, an Ohioan, as secretary, choosing instead a westerner, former Seattle mayor Richard A. Ballinger. Roosevelt was surprised at the replacement, believing that Taft had promised to keep Garfield, and this change was one of the events that caused Roosevelt to realize that Taft would choose different policies. Roosevelt had withdrawn much land from the public domain, including some in Alaska thought rich in coal. In 1902, Clarence Cunningham, an Idaho entrepreneur, had found coal deposits in Alaska, and made mining claims, and the government investigated their legality. This dragged on for the remainder of the Roosevelt administration, including during the year (1907–1908) when Ballinger served as head of the General Land Office. A special agent for the Land Office, Louis Glavis, investigated the Cunningham claims, and when Secretary Ballinger in 1909 approved them, Glavis broke governmental protocol by going outside the Interior Department to seek
