The U.S. Supreme Court on Tuesday declined to block a judge's ruling that requires the U.S. government to evaluate moving up to 837 potentially at-risk prisoners out of a federal prison in Ohio due to concerns about the health risks of the coronavirus. The justices rejected a request by President Donald Trump's administration to put the lower court ruling on hold. The brief order noted that three of the nine-member court's conservatives - Justices Clarence Thomas, Samuel Alito and Neil Gorsuch - would have granted the administration's request.
