"For Republican Sen. John Sherman of Ohio, chief sponsor of the Sherman Antitrust Act of 1890, the power of trusts amounted to a kingly prerogative, inconsistent with our form of government." Sherman reasoned that "if we will not endure a king as a political power, we should not endure a king over the production, transportation and sale of any of the necesaries of life."
