Why was William howard Taft considered a trust buster?

William Howard Taft was considered a trust buster primarily because of his aggressive enforcement of antitrust laws during his presidency from 1909 to 1913. He continued and expanded upon the antitrust efforts initiated by his predecessor, Theodore Roosevelt, by bringing numerous lawsuits against monopolies, including significant cases against Standard Oil and American Tobacco Company. Taft's administration filed more antitrust suits than Roosevelt's, solidifying his reputation as a dedicated opponent of corporate monopolies and promoting fair competition.
