I’ll see if I can’t find something on the National Guard control, too. That article could have been correct about McCain making a request of Washington but McCain could have been doing a Fed suck butt routine.
Regarding confiscation of guns or anything else that is unconstitutional, Arizona can “just say NO”. People aren’t going to just give them up anyway.
I would like to point out that, as a Senator, he did not have the authority to call out the Guard, since he is not Governor. :) It was likely just a PR stunt for the election year.
