How did Roosevelt fight against trusts and monopolies?

President Theodore Roosevelt fought against trusts and monopolies through vigorous enforcement of antitrust laws, notably the Sherman Antitrust Act. He initiated lawsuits against major corporations, such as the Northern Securities Company, to break up monopolistic practices and promote fair competition. Roosevelt also championed regulatory measures, establishing the Interstate Commerce Commission and the Bureau of Corporations to oversee and regulate industries. His approach, often termed "trust-busting," aimed to ensure economic fairness and protect consumers.
