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.
