As progressives gained strength on the state level, they turned to national politics. Little headway was made, however, since conservatives controlled the Senate. Some progress was made against the trusts during Theodore Roosevelt's administration, and Congress passed two bills regulating railroads, the Elkins Act (1903) and the Hepburn Act (1906). The exposés of business practices by the muckrakers aroused public opinion. The Pure Food and Drug Act and the Meat Inspection Act were passed (1906) to eliminate the worst practices of the food industry. Although Roosevelt supported the progressive drive for regulation of corporations and for social-welfare legislation, Congress remained adamant.
Roosevelt's successor, William Howard Taft, was a determined opponent of progressive reform; in 1911 progressives, whose ranks had been swelled by middle-class professionals, small businessmen, and farmers, formed the National Progressive Republican League to prevent Taft's renomination. When this failed, progressives united in a third party (see Progressive party) and nominated (1912) Roosevelt for President. Although Roosevelt was defeated, the new President, Woodrow Wilson, sponsored many progressive measures. The Federal Reserve Act of 1913 reformed the currency system; the Clayton Antitrust Act and the Federal Trade Commission Act (1914) extended government regulation of big business; and the Keating-Owen Act (1916) restricted child labor.
