It seems that President Biden believes he has the authority to order people to get the COVID-19 vaccines:

Biden expresses frustration over the unvaccinated, says ‘a distinct minority’ is keeping the U.S. from overcoming the coronavirus

President Biden announced sweeping new vaccine mandates Thursday that will affect tens of millions of Americans, ordering all businesses with more than 100 employees to require their workers to be inoculated or face weekly testing.

Biden also said he was requiring all health facilities that accept Medicare or Medicaid funding to vaccinate their workforces, which the White House believes will impact 50,000 locations.

And the president announced he would sign an executive order that would require all federal employees to get vaccinated against the coronavirus — without an option for those who prefer to be regularly tested instead — in an effort to create a model he hopes state governments and private companies will adopt.

The cluster of new policies comes as the country grapples with the highly contagious delta variant, which has sent cases surging to more than 150,000 a day and is causing more than 1,500 daily deaths. The White House has struggled to convince hesitant Americans to get vaccinated and has been increasingly shifting toward requirements.

In remarks from the White House, Biden took a more antagonistic tone toward the unvaccinated than he has in the past, as he turned from cajoling toward compulsion and blamed those who refuse to get shots for hurting those around them.

Yeah, that’s going to persuade people who haven’t wanted to get vaccinated to do so!

There’s more at the original, but the Washington Post article never stated under what legal authority the President claims he can order private businesses to do this. The New York Times said that:

The requirements will be imposed by the Department of Labor and its Occupational Safety and Health Administration, which is drafting an emergency temporary standard to carry out the mandate, according to the White House.

An obvious question: if getting vaccinated is so important, why did Mr Biden only order it for companies with 100 or more employees?

There’s at least one more day of the special session of the Kentucky General Assembly; I would suspect that the legislators would quickly put together a bill banning all state employees from in any way assisting OSHA in enforcing this order of the President’s/
