Wilson signed into law the Clayton Antitrust Act of 1914, named after its chief congressional sponsor, U.S. Representative Henry De Lamar Clayton Jr. This law extended federal authority that began with the Sherman Antitrust Law of 1890. Under the Clayton Anti-Trust Act, Congress could regulate price discrimination and mergers and acquisitions that led to monopolistic tendencies. The law also provided a safe harbor for union activities, such as strikes and pickets.
