DES MOINES, Iowa — Iowa lawmakers have paved the way for the nation's most restrictive abortion legislation in the country.
The Republican-majority Iowa Senate fast-tracked a vote early Wednesday morning on a so-called "heartbeat" bill that seeks to ban most abortions once a fetal heartbeat is detected. The GOP-controlled Iowa House approved the bill hours earlier.
The legislation effectively would ban most abortions around six weeks of pregnancy. Critics say that would ban the medical procedure before some women know they're pregnant.
Republican Gov. Kim Reynolds hasn't indicated whether she'll sign the bill into law. If enacted, the legislation is expected to be challenged in court over whether it violates U.S. Supreme Court rulings, including the landmark 1973 Roe v. Wade decision that legalized abortion.
Iowa Republicans passed legislation last year that banned most abortions after 20 weeks of pregnancy.
