Abortion-rights supporters announced a lawsuit Wednesday challenging Missouri abortion restrictions a day after voters enshrined abortion rights in the state constitution.

Voters narrowly approved Amendment 3 on Nov. 5, which adds a “fundamental right to reproductive freedom” to the state constitution, threatening to undo decades of pro-life gains.

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.
