Soft money contributions were generally made illegal in the United States in 2002 with passage of the McCain-Feingold Campaign Finance Reform Act, but opponents of the bill managed to create a number of loopholes through amendments. Previously, President George W. Bush had indicated absolute opposition to the bill, but as it was passed in the midst of the corporate scandals of 2002, a public relations nightmare for the Republican Party, and in particular at a time when allegations of impropriety were being levied against Vice President Dick Cheney for his dealings with Enron, Bush quietly signed it.
