I had thought that President Biden was only going to issue a mask mandate that lasted 100 days,
President-elect Joe Biden, who plans to make the coronavirus pandemic his top priority, will begin his presidency by asking Americans to wear masks for 100 days and requiring their use on federal property.
His first executive order, the "100 Days Masking Challenge," will symbolize the administration's sharp turn from the Trump era by emphasizing recommendations by public health experts. A president cannot tell states or cities what to do, but a federal mandate will affect federal offices and federal lands and will urge states to do the same.
but in reading the executive order, there appears to be no sunset, and no limitation and if it isn't rescinded the expectation is that we'll always be expected to wear masks on federal lands and in federal buildings.
So, from a legal standpoint, does this executive order necessarily need to be rescinded, does it go away when the CDC no longer recommends masking or does it remain perpetually?
