I read that PFL blog. I was struck by the summary at the end.
"Perhaps more importantly, President Trump should act. He should remind these elite bureaucrats that the American people put him in charge and that the American people have the final sign-off on the rules that govern their lives. Going forward, the president should require that only Senate-confirmed officials sign-off on his administration’s rules.
With a pen-stroke, President Trump could take power from deep-state bureaucrats and give it back to the American people."
Not to be picky, but if 98% of regulations are unconstitutional, it's not up to the executive branch to create any new rules to correct that. The judicial branch would have made that finding long ago as they're the ones responsible for determining if an action, regulation, or law is unconstitutional. And they're already ruled in cases like Chevron that agencies are empowered to create such rules and regulations under the authority granted them by Congress. It's sorta settled law.
Claiming only politically-connected Senate confirmed officials can sign a regulation makes no sense, as the publication of any regulation already falls under their ultimate responsibility as it already is. When regulations are challenged in court, among the named officials isn't the guy in room 3042 down the hall who typed it, but the Commissioner of the agency who's being called to account before the court. So yes, the Senate approved official is ultimately responsible. But to expect that every regulation and rule needs specific comprehensive review and signature by the Commissioner or whoever heads every agency would mean nothing ever gets done (as attractive as tat may sound, it's really not such a great thing) and not alter their current liability in court which already exists.
