The Missouri Senate signed off on legislation that expands the requirements of the state's 24-hour waiting period for abortions.
The bill would require abortion clinics to give women specific details about the development of fetuses and offer them a chance to see an ultrasound and listen to a heartbeat.
The legislation goes to the House, which, earlier this year, passed its own version of a bill expanding the informed consent law.
The House bill goes much farther, making it a crime to coerce a woman into having an abortion and requiring abortion clinics to tell prosecutors when teenagers seek abortions.
Advocates said it's a way to get leads on rapists.
