After the 1902 elections, Roosevelt called for a ban on railroad rebates to large industrial concerns, as well as for the creation of a Bureau of Corporations to study and report on monopolistic practices. To pass his antitrust package through Congress, Roosevelt appealed directly to the people, casting the legislation as a blow against the malevolent power of Standard Oil. Roosevelt's campaign proved successful, and he won congressional approval of the creation of the Department of Commerce and Labor, which included the Bureau of Corporations. The Bureau of Corporations was designed to monitor and report on anti-competitive practices; Roosevelt believed that large companies would be less likely to engage in anti-competitive practices if such practices were publicized. At Knox's request, Congress also authorized the creation of the Antitrust Division of the Department of Justice. Roosevelt also won passage of the Elkins Act, which restricted the granting of railroad rebates.
