Kentucky, Ohio, and Tennessee sued the Biden Administration Wednesday in response to the COVID-19 vaccine mandate issued for federal contractors. Kentucky Attorney General Daniel Cameron filed the suit, calling the mandate “unlawful and unconstitutional.”

The Occupational Safety and Health Administration (OSHA) laid out the requirements, ordering companies with 100 or more employees to have those employees vaccinated by Jan. 4 or otherwise be subject to weekly testing. The administration said that this mandate will protect more than 84 million workers from the spread of COVID-19 while on the job. Companies that fail to implement and enforce the mandatory policy within the 30-day time frame could face heavy fines.

OSHA anticipates the mandate to be in effect six months from the date of publication in the Federal Register. They have initiated a 30-day public comment period to assess whether any aspect of the mandate will become a final rule.

Indiana Attorney General Todd Rokita announced today that he will also file a lawsuit with Louisiana and Mississippi asking the federal government to overturn the mandate. This announcement comes after Indiana Governor Eric Holcomb issued a statement directing the Department of Labor to work with the Attorney General, calling the mandate an overreach.

Rokita and other attorneys general argue that this executive order lacks congressional authorization and will directly affect one-fifth of the workforce and will indirectly affect the entire economy. Rokita is planning to file two more lawsuits against OSHA in the coming days.
