What is happening with Biden's vaccine mandates?

Well, Biden put in place a mandate for employers to vaccinate or test, on a weekly basis their employees, if they have more than 100 of them. And there's been pushback from a lot of corners of society. Some smaller businesses have objected. Some governors, particularly Texas, Louisiana, have objected.

Texas said the mandate doesn't apply for large employers in its state, even though that puts the employers in a terrible situation of having to choose which level of government they should listen to. And these states have sued in federal courts. The federal courts have stayed the mandate, meaning it won't be implemented until the decision is made probably by the Supreme Court on the grounds that the Labor Department overstepped its authorities in issuing this mandate, claiming that they have the ability to protect workplace safety.
