Missouri abortion amendment

In November, Missourians will be asked whether they want to repeal the abortion rights amendment they approved in 2024 and reinstate an abortion ban. Unions and reproductive rights groups already worked together to defeat Amendments 4 and 5 in the August election.

Planned Parenthood clinics in Kansas City, Columbia and St. Louis restarted procedural abortions in 2025. All four clinics, along with the Planned Parenthood in Gladstone, also offer medication abortion.

The Stop the Ban campaign has raised more than $6.5 million. The leading political action committee on the other side, called Her Health, Her Future PAC, has raised just over $1 million as of last week.

Missouri residents overwhelmingly voted against proposals to eliminate the income tax and change how citizens can change the Missouri constitution. Meanwhile, Kansans elected Reverend Adam Hamilton as the Democratic opponent to U.S. Sen. Roger Marshall and Democrat Cindy Holscher and Republican Ty Masterson will face each other in the race for Kansas governor.

Missouri polling places are open from 6 a.m.-7 p.m. on Election Day, Aug. 4. See results as they come in for U.S. House primary contests and constitutional amendment questions.

Amendment 4 would require any constitutional amendment put on the ballot through the initiative petition process to pass in all eight congressional districts, rather than by a simple majority. Missouri voters in recent years have passed amendments like abortion rights and marijuana legalization that were opposed by Republican lawmakers.

A Planned Parenthood clinic in Springfield began providing medication abortion Monday while also expanding pain management for IUD placements and biopsies. It's the fifth clinic to begin offering the service after a June court decision struck down Missouri's restrictions.

This is the first time that Planned Parenthood's Gladstone clinic has ever offered medication abortion, after a judge struck down Missouri's restrictions on mifepristone. Officials said that appointments "filled quickly."

Following the Thursday ruling by a Jackson County judge, Planned Parenthood in Kansas City began providing medication abortions to patients on Monday for the first time since 2018. But affiliates are still fighting limitations as critics again seek to restrict access via a ballot issue in November.

Judges increasingly have found that official summaries from Missouri election officials fail to tell voters what ballot measures would actually do — forcing rewrites on amendments about abortion, redistricting and more. Republicans say courts are overstepping.

The November measure would essentially reinstate Missouri's abortion ban by repealing the reproductive rights amendment voters approved in 2024. It would also add a constitutional ban on gender-affirming care for minors.

An amendment banning abortion will go before Missouri voters in November, possibly alongside a referendum on the state's gerrymandered congressional map. But a proposal to expand sales taxes and eliminate the income tax will appear in the smaller-turnout August election.
