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.

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.

State Rep. Bruce Skaug (R) introduced a proposal to raise the voting threshold for ballot initiatives, saying that requiring 60% of the vote for amendments to pass would "level the playing field."

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