The Supreme Court is hearing arguments on Friday on the legality of two initiatives at the heart of the Biden administration’s efforts to address the coronavirus in the workplace through vaccine mandates.
The challengers — states led by Republican officials, businesses, religious groups and others — say Congress has not authorized the measures, adding that they are unnecessary and in some ways counterproductive.
The administration says that workplace safety and health care laws have given it ample authority to take bold action in the face of a lethal pandemic.
