A federal appeals court on Tuesday, Sept. 21, 2021, will consider whether Missouri can implement a sweeping law aimed at limiting abortions. The law adopted in 2019 would ban abortions at or around the eighth week of pregnancy. It also would prohibit abortions based on a Down syndrome diagnosis. (AP Photo/Jeff Roberson, File)
