The House took the first step to forcing a 72-hour abortion waiting period into law early in the evening. The Senate began debating the measure soon after and passed it at about 11:30 p.m. Central Time.
The House voted 117-44 to overturn Gov. Jay Nixon's veto of House Bill 1307. The Senate voted 23-7. The legislation extends the state's current 24-hour waiting period. Missouri becomes only the third state in the nation with a three-day period, along with South Dakota and Utah.
