Given where things are in DC and the limits on executive power, not much else he can do right now. Especially if the Supreme Court limits OSHA's ETS powers. He's really stuck if OSHA gets its wings clipped.
I agree with this.
Legal experts told us early on that state governments have broad powers to protect public health during a health emergency (e.g., setting quarantines, business restrictions, gathering limitations and personal protection measures), while the power of the federal government is limited by law and legal precedent.
We also found out early that the use of emergency health powers would vary among the states. Some states took aggressive action. Others left key decisions to local governments, and a few restricted the imposition of certain measures at the local level.
I wish the feds had done much more to support the states and local health authorities in controlling the spread of the virus. I think the Trump and Biden administrations both dropped the ball when it came to providing leadership and funding for things like testing, PPE, improved ventilation and contact tracing.
