Taft stumbled dramatically on two important occasions as President. The first misstep occurred with his special congressional session to revise the tariff downward. This move activated a concerted effort by the protectionist majority in the Republican Party to persuade Taft to back off on tariff reform. In the struggle over the tariff, Senator Nelson Aldrich of Rhode Island and Representative Sereno E. Payne of New York, representing big business, succeeded in pushing through a tariff (the Payne-Aldrich Tariff) that affected only modest reductions. Although during the course of congressional action Taft had threatened to veto a tariff bill with insufficient reductions, when the Payne-Aldrich bill came to his desk he signed it, later claiming it was the best tariff bill ever passed by Congress. Taft's reversal on tariff reform immediately alienated progressives who saw high tariffs as the "mother of trusts."The second misstep involved his dismissal of Roosevelt's friend, the chief forester of the United States, Gifford Pinchot. The affair stemmed from Taft's appointment of Washington-state businessman Richard Ballinger as head of the Department of the Interior. Ballinger held that Roosevelt had improperly closed large sections of federal public-domain lands to economic development, re-opened some tracts, including rich coal lands in Alaska that Roosevelt had previously designated not for sale. Consequently, Pinchot launched a public attack on Ballinger, and indirectly on Taft, leaving the President with no alternative but to dismiss Pinchot. The resulting explosion tore the Republican Party apart and drove an inseparable wedge between Taft and his once-beloved friend and mentor, Theodore Roosevelt.
