War I and now sought to capture some of their industry's wartime gains. Attorney General A. Mitchell Palmer invoked the Lever Act, a wartime measure that made it a crime to interfere with the production or transportation of necessities. The law, meant to punish hoarding and profiteering, had never been used against a union. Certain of united political backing and almost universal public support, Palmer obtained an injunction on October 31 and 400,000 coal workers went on strike the next day. He claimed the President authorized the action, following a meeting with the severely ill President in the presence of his doctor. Palmer also asserted that the entire Cabinet had backed his request for an injunction. That infuriated Secretary of Labor Wilson who had opposed Palmer's plan and supported Gompers' view of the President's promises when the Act was under consideration. The rift between the Attorney General and the Secretary of Labor was never healed, which had consequences the next year when Palmer's attempts to deport radicals were frustrated by the Department of Labor. Samuel Gompers, President of the American Federation of Labor, protested that President Wilson and members of his Cabinet had provided assurances when the Act was passed that it would not be used to prevent strikes by labor unions. He provided detailed accounts of his negotiations with representatives of the administration, especially Secretary of Labor William B. Wilson. He also argued that the end of hostilities, even in the absence of a signed treaty, should have invalidated any attempts to enforce the Act's provisions. Nevertheless, he attempted to mediate between Palmer and Lewis, but after several days called the injunction "so autocratic as to stagger the human mind". The coal operators smeared the strikers with charges that Lenin and Trotsky had ordered the strike and were financing it, and some of the press echoed that language. Others used words like "insurrection" and "Bolshevik revolution". Eventually Lewis, facing criminal charges and sensitive to the propaganda campaign, withdrew his strike call, though many strikers ignored his action. As the strike dragged on into its third week, coal supplies were running low and public sentiment was calling for ever stronger government action. Final agreement came on December 10. Reactions Palmer Raids Despite two attempts on his life in April and June 1919, Attorney General A. Mitchell Palmer moved slowly to find a way to attack the source of the violence.
