The Biden administration is facing a legal challenge that could restrict access to the leading abortion drug in the U.S. A 19th century “anti-vice” law, the Comstock Act, has been revived by anti-abortion groups and conservative states in an effort to block the mailing of mifepristone. HHS Secretary Xavier Becerra has said that all options are on the table to ensure access to the drug, including Supreme Court intervention. Pro-choice advocates have criticized the ruling, arguing that it will have a negative impact on women’s health and rights.
