Iowa lawmakers on Wednesday passed the strictest abortion legislation in the U.S., sending the legislation to Gov. Kim Reynolds’s (R) desk.
The legislation, known as the heartbeat bill, aims to block abortions once a heartbeat is detected, which would essentially ban the procedure for most by the sixth week of pregnancy.
The legislation has faced fierce opposition, with critics saying the measure would make a woman unable to get an abortion before they even know they’re pregnant.
If signed into law, the measure is expected to be legally challenged on whether it goes against past Supreme Court rulings, such as Roe v. Wade, which legalized the procedure.
