Arkansas lawmakers have approved the harshest anti-abortion law in the country. On Wednesday, the state General Assembly voted to override Democratic Gov. Mike Beebe’s veto of a measure banning abortion after 12 weeks of pregnancy, the point at which an abdominal ultrasound can detect a fetal heartbeat. Opponents expect the law to be overturned before it can take effect later this year. Federal law gives women the right to abortion up to 24 weeks of pregnancy, double the Arkansas limit.
