 Taft continued and expanded Roosevelt's efforts to break up business combinations through lawsuits brought under the Sherman Antitrust Act, bringing 70 cases in four years (Roosevelt had brought 40 in seven years). Suits brought against the Standard Oil Company and the American Tobacco Company, initiated under Roosevelt, were decided in favor of the government by the Supreme Court in 1911. In June 1911, the Democrat-controlled House of Representatives began hearings into United States Steel (U.S. Steel). That company had been expanded under Roosevelt, who had supported its acquisition of the Tennessee Coal, Iron, and Railroad Company as a means of preventing the deepening of the Panic of 1907, a decision the former president defended when testifying at the hearings. Taft, as Secretary of War, had praised the acquisitions. Historian Louis L. Gould suggested that Roosevelt was likely deceived into believing that U.S. Steel did not want to purchase the Tennessee company, but it was in fact a bargain. For Roosevelt, questioning the matter went to his personal honesty.
