A second set of states has filed a federal lawsuit challenging the Biden administration's COVID-19 vaccine mandate for health care workers. The suit filed in Louisiana on behalf of 12 states was dated Monday. It comes less than a week after another lawsuit challenging the rule was filed in Missouri by a coalition of 10 states. Both lawsuits say the rule issued by the Centers for Medicare and Medicaid Services violates federal law and unconstitutionally encroaches on powers reserved to the states. In addition to Louisiana, the latest suit covers Montana, Arizona, Alabama, Georgia, Idaho, Indiana, Mississippi, Oklahoma, South Carolina, Utah and West Virginia.
