In late October 2019, US Senator Jim Inhofe introduced the Down Syndrome Discrimination by Abortion Prohibition Act. The Act would prohibit abortion based on an unborn child having Down Syndrome. (Here is a link to press release from Senator Inhofe.) Companion legislation was also introduced in the House.
A number of states have passed similar laws, although several laws have been struck down by the courts. The Pennsylvania legislature recently passed a similar law but Pennsylvania’s Governor vetoed the law on Thursday November 21, 2019.
