The Republican supermajority in the Missouri Legislature contends rolling back some, if not all, of the abortion rights protected under the new amendment still adheres to voters’ wishes.

The constitutional amendment approved by Missouri voters protects abortion access until the point of fetal viability, when a fetus can survive on its own outside the womb without extraordinary medical interventions.

Some Republican lawmakers say they want to address the definition of "fetal viability" in the new law. Others want to go back to voters.
