"The National Guard, funded by the federal government, occupying property leased to the federal government, using weapons owned by the federal government, punishing trespassers under federal law, is a state militia."
I have to remember that one. I alse read somewhere that the Congressional Record has a statement that Congress made when it passed the NG enabling statutes back in th eearly 1900's. This statement was to the effect that Congress' power to pass the NG statute came from its "standing armies" authority under the Constitution.
I will have to do some digging . . . .
