Alabama Attorney General Steve Marshall on Friday expressed disappointment over the U.S. Supreme Court decision that preserves the use of the common abortion pill mifepristone as the legal battle over the medication continues.

“While I am disappointed that the stay has remained in place, I am confident the appeals process will reinforce that President Biden lacked the authority to enact a dangerous mail-order abortion regime,” Marshall said in a statement issued Friday evening. “As the last line of defense against President Biden’s radical agenda, I will continue to do everything in my power to protect mothers and the life of the unborn.”

The Supreme Court granted emergency requests from the Biden administration and New York-based Danco Laboratories, maker of the drug mifepristone. They are appealing a lower court ruling that would roll back Food and Drug Administration approval of mifepristone.

The drug has been approved for use in the U.S. since 2000 and more than 5 million people have used it. Mifepristone is used in combination with a second drug, misoprostol, in more than half of all abortions in the U.S.

The court had a self-imposed Friday night deadline to decide whether women’s access to a widely used abortion pill will stay unchanged or be restricted while a legal challenge to its Food and Drug Administration approval goes on.

The justices weighed arguments that allowing restrictions contained in lower-court rulings to take effect would severely disrupt the availability of the drug, mifepristone, which is used in the most common abortion method in the United States.
