The Unborn Victims of Violence Act was first introduced in Congress in 1999 by then-Congressman (later Senator) Lindsey Graham (R-SC). It passed the House of Representatives in 1999 and 2001, but not the Senate. In 2003, the bill was reintroduced in the House as H.R. 1997 by Rep. Melissa Hart of Pennsylvania. It was ultimately co-sponsored by 136 other members of the House before it passed by a vote of 254 in favor to 163 against on February 26, 2004. After several amendments were rejected, it was passed in the Senate by a vote of 61-38 on March 25, 2004. It was signed into law by President George W. Bush on April 1, 2004.
