In Louisiana, lawmakers approved a bill Wednesday that would ban abortions once a fetal heartbeat can be detected, becoming the latest state to challenge the Supreme Court’s landmark 1973 ruling, Roe v. Wade. Louisiana House lawmakers voted 79 to 23 for the bill, which outlaws abortions as early as six weeks into a pregnancy, while providing no exemptions to people who become pregnant by rape or incest. The state’s Democratic governor, John Bel Edwards, has promised to sign the bill into law.
