Pain-Capable Unborn Child Protection Act This bill amends the federal criminal code to make it a crime for any person to perform or attempt to perform an abortion if the probable post-fertilization age of the fetus is 20 weeks or more. A violator is subject to criminal penalties—a fine, up to five years in prison, or both. The bill provides exceptions for an abortion: (1) that is necessary to save the life of the pregnant woman, or (2) when the pregnancy is the result of rape or incest. A physician who performs or attempts to perform an abortion under an exception must comply with specified requirements. A woman who undergoes a prohibited abortion may not be prosecuted for violating or conspiring to violate the provisions of this bill.
