Eleven states filed suit Friday against the Biden administration, challenging the constitutionality of a new mandate that businesses with 100 or more employees force their workers to get the COVID-19 shot. “This mandate is unconstitutional, unlawful, and unwise,” said the court filing by Missouri Attorney General Eric Schmitt. Missouri has 3,443 private employers who could be covered by the vaccine requirement, with nearly 1.3 million employees.
