Since when does the CDC have any authority/control over anyone? They are not a government agency but a private organization with close government ties. All they can legally do is give advice. And that, lately, has been less than worthless.
From someone online in response to this latest b.s.: CDC Announces All Travelers (on public transport) Must Wear Two Masks, Threatens Arrest
"The CDC has no power to issue any criminal penalties. “…its power to act is extremely restricted. The agency traditionally acts in an advisory role and can only take control from local authorities under two circumstances: If local authorities invite them to do so or under the authority outlined in the Insurrection Act in the event of a total breakdown of law and order."
