Oklahoma lawmakers on Thursday approved a bill making it a felony for doctors to perform abortions, which opponents say is essentially a ban on the procedure.
The Republican bill, which has been called the first of its kind nationally, will now be sent to the desk of GOP Gov. Mary Fallin. She has five days to sign or veto the bill before it automatically becomes law.
The bill is all but certain to wind up in court if it wins approval from Fallin, who has typically supported anti-abortion-rights measures.
Critics of the bill have long warned the provision is unconstitutional, and have threatened to take legal action if it is enacted.
