Application for stay presented to Justice Kagan and by her referred to the Court is granted, and the district court's April 8, 2019 order granting a preliminary injunction is stayed pending the timely filing and disposition of a petition for a writ of certiorari. Should the petition for a writ of certiorari be denied, this stay shall terminate automatically. In the event the petition for a writ of certiorari is granted, the stay shall terminate upon the sending down of the judgment of this Court. Justice Sotomayor would deny the application.
