The Missouri Senate is the latest U.S. state legislative body to act in favor of a restrictive abortion ban bill, bolstering a national movement Republicans hope could lead to the revocation of the landmark 1973 decision that legalized abortion. 

The Republican-led Senate in the Midwestern state voted 24-10 early Thursday to ban abortions after eight weeks of pregnancy. The legislation includes exceptions for medical emergencies but not for pregnancies caused by incest or rape. 

The state's Republican-led House must approve the measure before it goes to Republican Gov. Mike Parson for him to sign into law. Parson voiced support for the bill Wednesday. 

The Missouri Senate's passage of the bill came hours after Republican Alabama Gov. Kay Ivey signed into law a near-total ban on abortion. 

"To the bill's many supporters, this legislation stands as a powerful testament to Alabamians' deeply held belief that every life is precious and that every life is a sacred gift from God,'' Ivey said in a statement. 

Lawmakers in the southeastern U.S. state had passed the legislation Tuesday, sparking a legal fight over a measure that became one of the nation's most stringent abortion laws.

The Planned Parenthood Federation of America vowed Wednesday to challenge the legislation in court. "We have no choice," said President Leana Wen. "We are talking about the rights for generations to come."

Alabama's Republican-dominated Senate voted 25-6 to make performing an abortion at any stage of pregnancy a felony punishable by up to 99 years or life in prison for the abortion provider, although women seeking or undergoing an abortion would not be punished. The only exception would be when the woman's health is at serious risk.

Senators rejected an attempt to add an exception for rape and incest.

Supporters said the bill was designed to spark litigation that could lead to the U.S. Supreme Court overturning the landmark 1973 decision that legalized abortion.

"Roe v. Wade has ended the lives of millions of children," said Alabama Republican Sen. Clyde Chambliss. "This bill has the opportunity to save the lives of millions of unborn children."

Other states

Emboldened by the Supreme Court's new conservative justices, Kentucky, Mississippi, Ohio and Georgia have approved bans on abortion once a fetal heartbeat is detected, which can occur in about the sixth week of pregnancy. And abortion opponents in several other states are seeking to challenge abortion access.

The speaker of the U.S. House of Representatives, Democrat Nancy Pelosi of California, told reporters Thursday that the Republican-led efforts were "dismantling and sabotaging" women's health care rights. "I don't want to be a fearmonger," she said, "but I do believe that they're trying to go in a path to totally dismantle Roe v. Wade."

In an interview Wednesday on CNN, New York Sen. Kirsten Gillibrand, a Democratic presidential candidate, said, "This is a plan by the Republican Party, make no mistake, to overturn Roe v. Wade and turn back the clock on women's reproductive civil and human rights."

Another Democratic presidential candidate, former Vice President Joe Biden, said the current law should not be declared unconstitutional.

"Roe v. Wade is settled law and should not be overturned," Biden said. "The choice should remain between a woman and her doctor."

A Pew Research Center poll conducted late last year found that 58 percent of those surveyed said abortion should be legal in almost all cases while 37 percent said it should be unlawful.
