James Lankford actually said...

If we no longer have predictability in law and regulations, where things are going, it is a problem to us long term.

I think all too often, Congress abrogates its responsibility on oversight of regulation to the judiciary, creating further uncertainty.

does that create opportunities from here on out for the Executive Branch and all agencies to move through the vagaries of every rule

More hearings like this one will be necessary for Congress to begin to reclaim what it has lost.
