A law restricting the federal funding of abortion that Democratic nominee Hillary Clinton supports repealing is credited by a recent study with saving more than 2 million lives.

The Hyde Amendment, a federal law passed almost exactly 40 years ago in September 1976, prohibits the federal coverage of most abortion procedures.

Hyde is credited with preventing the abortion of approximately 2 million people over the past four decades, according to a report published by the pro-life research group the Charlotte Lozier Institute.
