SPARTANBURG, S.C./LOS ANGELES (Reuters) – Democratic presidential candidate Kamala Harris unveiled a new plan to protect abortion access on Tuesday, joining fellow White House hopefuls pushing back against Republican-backed state laws that restrict a woman’s right to end a pregnancy. The U.S. senator from California said if elected president she will force states with a history of hostility toward Roe v. Wade – the landmark 1973 Supreme Court decision that established a woman’s right to an abortion – to first obtain approval from the Justice Department before a law restricting abortion could take effect. “Here’s the thing, there are states that keep passing these laws,” Harris said at a Tuesday night town hall hosted by MSNBC in Spartanburg, South Carolina.
