Dunwoody, Ga. — Herschel Walker, who has vehemently opposed abortion rights as the Republican nominee for U.S. Senate in Georgia, paid for an abortion for his girlfriend in 2009, according to a new report published late Monday. The candidate called the accusation a "flat-out lie" and said he would sue. The Daily Beast spoke to a woman who said Walker paid for her abortion when they were dating. The news outlet reviewed a receipt showing her $575 payment for the procedure, along with a get-well card from Walker and her bank deposit records showing the image of a $700 personal check from Walker dated five days after the abortion receipt. The woman said Walker encouraged her to end the pregnancy, saying that the time wasn't right for a baby, The Daily Beast reported.
