The increase in Republican majorities in the Senate and House after the 2004 elections breathed new life into the bill, which was introduced in its current form by the chairman of the Senate Finance Committee, Republican Senator Chuck Grassley of Iowa. According to George Packer in his book "The Unwinding", Joe Biden, Chris Dodd, and Hillary Clinton helped pass this bill. (Of the three, however, only Biden voted for the final bill. Dodd voted against, and Clinton did not vote.) The bill was supported by President George W. Bush. Tom DeLay also championed the legislation. The bill passed by large margins, 302-126 in the House and 74-25 in the Senate, and was signed into law by President Bush.
