After having checked both the Texas *and* United States Constitutions and you'll find that the Governor of Texas does have substantial command authority over the Texas Army and Air National Guard but the President of the United States has *ultimate* command authority over every uniformed member of the United States Armed Forces...including the Texas National Guard.Osama Obama could overrule any order given by Perry with a 30 second phone call.So could the Secretary of the Army or the Secretary of the Air Force.
The Texas National Guard and the Texas State Guard are two entirely separate entities. Obama has no authority over the Texas State guard. Perry can deploy them and the President can do nothing about it.
Its all moot anyway because Perry is a complete Globalist sellout and will do nothing to impede the 3rd World invasion.
The federal executive has no authority over the Texas State Guard.
The federal executive has no authority over the Texas reserve militia.
The federal executive does have authority over the Texas Army National Guard and the Texas Air National Guard only when they are called into actual service of the United States. At all other times the Governor is the Commander in Chief of these forces.
