A proposed abortion bill  introduced in Arkansas this week would ban all abortion services after a fetal heartbeat is detected — which can occur as early as six weeks, before some women even realize they’re pregnant — and charge doctors who perform abortions after that arbitrary cut-off with a Class D felony, punishable by up to six years in prison and up to a $10,000 fine.

GOP lawmaker Jason Rapert  filed the legislation on Monday, and half of Arkansas’ state senators — 18 of the Senate’s 35 total members — have already signed on as co-sponsors. Rapert says he may bring the bill before the Arkansas Senate’s Public Health Committee later this week.
