Missouri is the most populous state where a ballot measure could roll back a current ban on abortions at all stages of pregnancy.

When Missouri on Tuesday became the first state to overturn a near-total abortion ban by the vote of the people, Desiree White cried happy tears. Twenty-five years earlier, she and her husband chose to terminate a pregnancy they very much wanted after they received a diagnosis of a fatal fetal abnormality.

Abortion providers moved quickly to formally challenge the state’s abortion ban and other restrictions after voters approved Amendment 3.
