JEFFERSON CITY, Mo. (AP) — Missouri Republican lawmakers are brainstorming potential changes to abortion laws, including additional oversight and an idea that there should be memorials for aborted fetuses. House committee members Wednesday floated ways to revamp state policy after reviewing abortion practices in Missouri for months.

Democratic Attorney General Chris Koster and House and Senate committees launched investigations into Planned Parenthood this summer. The reviews followed the release of undercover videos by anti-abortion activists showing officials from the organization discussing the transfer of fetal tissue.

Koster says he found no evidence that a St. Louis Planned Parenthood sells fetal tissue. But GOP House committee leaders say they want to tighten regulations.

Policy ideas included one from GOP Representative Rick Brattin to create a “Vietnam Wall-type” memorial for aborted fetuses.
