Mifepristone, a common abortion-inducing drug, will remain approved but under more intense restrictions while a legal challenge proceeds, a federal appeals court ruled late Wednesday. The 5th U.S. Circuit Court of Appeals halted parts of a controversial court order that was set to go into effect Friday night, while affirming other parts. The Department of Justice said Thursday it will seek emergency relief at the U.S. Supreme Court to get the entire original order stayed.
