Cedar Rapids Gazette: A federal judge on Monday blocked President Joe Biden’s administration from enforcing a coronavirus vaccine mandate on thousands of health care workers in 10 states that had brought the first legal challenge against the requirement. The court order said that the federal Centers for Medicare & Medicaid had no clear authority from Congress to enact the vaccine mandate for providers participating in the two government health care programs for the elderly, disabled and poor. The preliminary injunction by St. Louis-based U.S. District Judge Matthew Schelp applies to a coalition of suing states that includes Alaska, Arkansas, Iowa, Kansas, Missouri, Nebraska, New Hampshire, North Dakota, South Dakota and Wyoming.
