(KTRS) – The Missouri Senator behind a bill that imposed a 72-hour waiting people before a woman can get an abortion, is proposing new restrictions on the procedure.

State Senator David Sater is proposing a bill that would prevent abortions solely because a test indicated the baby has or could develop Down syndrome. His bill would require doctor’s who perform the procedure in such cases to certify that they didn’t know an abortion was sought because of the diagnosis. A doctor who violates the provision could face up to a year in prison and a $1,000 fine.

Sater’s waiting period bill did not include exceptions for rape or incest victims.
