JEFFERSON CITY, Mo. (AP) — Missouri lawmakers enacted one of the nation’s most stringent abortion waiting periods Wednesday, overriding a veto of legislation that will require women to wait 72 hours after consulting with a doctor before ending a pregnancy.

The vote by Missouri’s Republican-led Legislature overrules the veto of Democratic Gov. Jay Nixon, who had denounced the measure as “extreme and disrespectful” toward women because it contains no exception for cases of rape or incest.

About half of the states, including Missouri, already have abortion waiting periods of 24 hours.

Missouri’s new law will be the second most-stringent behind South Dakota, where its 72-hour wait can sometimes extend even longer because weekends and holidays are not counted. Utah is the only other state with a 72-hour delay, but it grants exceptions for rape, incest and other circumstances.

Missouri lawmakers specifically rejected an amendment earlier this year that would have granted exceptions for rape and incest. Abortion opponents argued that it would have diminished the value of some lives depending on how they were conceived.

Missouri’s new waiting period law will take effect 30 days after the veto-override vote.

Planned Parenthood, which operates Missouri’s only licensed abortion clinic in St. Louis, has not said whether it will challenge the 72-hour waiting period court. But the organization has said its patients travel an average of nearly 100 miles for an abortion, and an extra delay could force them to either make two trips or spend additional money on hotels.

Women also could travel just across the state line in the St. Louis and Kansas City areas to abortion clinics in Illinois and Kansas that don’t require as long of a wait.

Missouri’s current waiting-period also lacks an exception for rape or incest. It requires physicians to provide women information about medical risks and alternatives to abortion and offer them an opportunity for an ultrasound of the fetus.

Before Missouri legislators voted on the measure, hundreds of people gathered Wednesday at the Capitol for competing rallies for and against the legislation. When it was originally passed in May, opponents staged a 72-hour, around-the-clock “citizen filibuster” on the Capitol steps.

Women who previously had abortions have spoken both in support and opposition of the longer waiting period.

Linda Raymond, of St. Louis, said she regrets the abortion she had 38 years ago and might have chosen to act differently if she had been offered information about alternatives, seen an ultrasound of the fetus and been required to take more time to think about her decision.

“A 72-hour time frame is compassionate for women,” Raymond said.

Liz Read-Katz, of Columbia, said she had an abortion after learning the fetus had a severe chromosomal defect.

“Waiting 72 hours wouldn’t have changed my mind, but it most definitely would have caused more pain both mentally and physically,” she said.

Missouri has a history of enacting abortion restrictions. Republican and Democratic lawmakers twice previously joined together to override vetoes of abortion bills — enacting what proponents referred to as a partial-birth abortion ban in 1999 and instituting a 24-hour abortion waiting period in 2003.

Three Missouri clinics have quit offering abortions in the past decade, and the number performed in Missouri has declined by one-third to a little over 5,400 last year.
