Oklahoma Attorney General John O’Connor said the state is preparing litigation against President Joe Biden's administration over sweeping COVID-19 vaccine mandates. On Thursday, Biden announced expansive rules mandating that all employers with more than 100 workers require them to be vaccinated or test for the virus weekly, affecting about 80 million Americans. And the roughly 17 million workers at health facilities that receive federal Medicare or Medicaid also will have to be fully vaccinated.Biden is also requiring vaccination for employees of the executive branch and contractors who do business with the federal government — with no option to test out. That covers several million more workers, the Associated Press reported. >> More on this: President Biden announces sweeping new vaccine mandates impacting 100 million workersO'Connor released a statement in response:"We respect the right of Oklahoma businesses and individuals to make health care decisions for themselves and their families. My office will vigorously oppose any attempt by the federal government to mandate vaccines. We are preparing litigation to stand up for our rights and defend the rule of law against the overreach of the federal government." Gov. Kevin Stitt also released a statement, saying that it’s not the government’s role to dictate private businesses what to do:“It is not the government’s role to dictate private businesses what to do. Once again President Biden is demonstrating his complete disregard for individual freedoms and states’ rights. As long as I am governor, there will be no government vaccine mandates in Oklahoma. My administration will continue to defend Oklahoma values and fight back against the Biden administration’s federal overreach.”>> COVID-19 in Oklahoma: New cases, deaths, breakthrough cases, vaccination rates
