Oklahoma Gov. Kevin Stitt has signed into law the nation’s strictest abortion ban. The ban, passed by state lawmakers last week, prohibits all abortions with few exceptions. Stitt signed the bill on Wednesday. Providers have said they will stop performing the procedure as soon as the bill is signed. The law is part of an aggressive push in Republican-led states to scale back abortion rights. The only exceptions included in the law are to save the life of a pregnant woman or if the pregnancy is the result of rape or incest that has been reported to law enforcement.
