Why is she shocked? Democrat state AGs pull this stuff all the time.
As for Ms. Collins’ vaunted intelligence, she sure has a funny way of showing it.
If, as it seems quite likely, the court will decide that the ACA is unconstitutional then Collins and her like minded legislators need to submit a bill that will address their concerns. Failure to defend a regulation/law in court is not new for the DOJ or any states AG’s that do not agree with the regulation/law. Happens all too frequently.
