The Gov is, until they are federalized. Then it’s POTUS. They will have to be pulled back, control returned to the states, then the Gov can call them out as the state contingent. Right now, they are federal troops, i.e., National Guard.
I am trying to remember the problem during Katrina of GWB calling out the Louisiana National Guard over the orders of the Governor. There is a law (can't remember the name of it or its exact contents) that says the federal government has to declare martial law in order for the federal government to take over the Guard.
