Missouri voters passed a voter-led ballot initiative enshrining abortion rights in the state constitution last year.

Senate Republicans used what's known as the "previous question" to end a filibuster to counteract two measures Missouri voters backed last year. The first measure would repeal Amendment 3 and replace it with language to ban most abortions. The other repealed paid sick leave requirements in a measure known as Proposition A.

Missouri voters passed abortion right protections in November 2024, but Republican lawmakers are looking to reinforce a ban on the reproductive care.
