"Obama administration then adopted a dubious legal theory that allowed it to make the payments even in the absence of a clear appropriation from Congress"
Clearly, this act was unconstitutional, however, a serious question arises--is the ACA constitutional?   Nothing says the US government can "take" from anyone to "give" to anyone else--be it individuals or businesses.   I hope Mr. Trump and company can repeal Obama Care (ACA) completely and start over.   Mr. Bagley, you are only right when you said: " What a stupid and unnecessary mess."
