 With a shift in public opinion for pro-campaign finance reform legislation during the Progressive era, congress enacted the Tillman Act in 1907, which banned direct corporate financing of political campaigns.This was followed with the enactment of the Federal Corrupt Practices Act (FCPA) of 1910, which was amended in 1911; providing two limitations on expenditures in federal elections.The first was that no candidate for Congress shall, in procuring his nomination and election, spend any sum in excess of the amount provided for by state law.
