Answer:
President Cleveland claimed that the strike violated the Sherman Antitrust Act,
Step-by-step explanation:
President Cleveland obtained a court injunction through the office of the United States attorney general claiming that the strike and demonstrations by the unions violated the Sherman Antitrust Act.
The pullman strike of 1984 was a railway strike which stopped railway operations. The aim of the strike was for the recognition of the American Railway Union by the Pullman Company and the American government. Eventually, after the court injunction was granted, troops were deployed to disrupt the strike action.
